Prepainted metal, often referred to as pre-coated metal or prefinished metal, is a type of metal substrate, usually steel or aluminum, that has been coated with a layer of paint or other protective finish before it is formed into final products. This process generally involves two main steps: 1. **Surface Preparation**: The metal is thoroughly cleaned and treated to ensure good adhesion and to prevent corrosion. This may include processes such as washing, phosphating, and applying a primer.
Continuous Cooling Transformation (CCT) refers to a metallurgical process that describes the changes in the microstructure of a material, usually steel, as it cools at a continuous, rather than an instantaneous or isothermal, rate. This process is significant in understanding how cooling rates affect the phase transformation and mechanical properties of steel.
Metallic objects are items made primarily of metal, a material characterized by its conductivity, malleability, ductility, and luster. Metals possess specific physical properties that make them unique, such as high density, shiny appearance, and ability to conduct heat and electricity. Common examples of metallic objects include: 1. **Utensils**: Spoons, forks, knives made of stainless steel or silver.
The Global Powder Metallurgy Property Database (GPMPD) is a comprehensive online resource that provides standardized data on the properties of materials used in powder metallurgy (PM). Powder metallurgy is a manufacturing process that involves the production of metal parts from powdered materials, typically involving pressing and sintering techniques. The GPMPD collects and compiles data on various materials, including metals, alloys, and other compounds used in PM applications.
Martensite is a microstructure that forms in steel and other alloys during rapid cooling or quenching from a high temperature. It is characterized by its unique arrangement of atoms, which creates a distinct, hard, and brittle phase. The formation of martensite occurs when austenite, a face-centered cubic phase of iron, is rapidly cooled to below a certain temperature, known as the martensite start temperature (Ms).
Metal casting is a manufacturing process in which liquid metal is poured into a mold to create a specific shape or form upon solidification. This technique is one of the oldest known methods of shaping metal and is widely used in various industries, including automotive, aerospace, and construction, due to its ability to produce complex shapes with high precision.
Nanocrystalline materials are materials that have a crystalline structure with grain sizes typically in the nanometer range, usually defined as being smaller than 100 nanometers (1 nanometer = 1 billionth of a meter). These materials can be composed of metals, ceramics, semiconductors, or other substances, and their unique properties stem from their small grain size, which significantly influences their mechanical, electrical, thermal, and optical characteristics.
In slang, "stringer" typically refers to a freelance journalist or writer who contributes articles or news stories to various media outlets on a temporary or irregular basis. These individuals often work independently rather than being employed full-time by a single publication. The term can also imply a certain level of expertise or niche focus, as stringers are usually expected to find and report on stories that may not be covered by larger media organizations.
Permeability in the context of foundry sand refers to the ability of the sand to allow gases and liquids to pass through it. This property is crucial in the foundry industry, especially in sand casting processes, where the sand mixture is used to create molds for metal casting. Here are some key points about permeability in foundry sand: 1. **Importance in Casting**: During the casting process, molten metal is poured into a mold made of sand.
Silver overlay is a decorative technique often used in jewelry, tableware, and other decorative items. The process typically involves applying a thin layer of silver over a base material, which can be made of metals such as brass or copper. This method provides the appearance of solid silver while being more cost-effective and lightweight. There are a few key points about silver overlay: 1. **Appearance**: The silver layer gives the item a shiny, attractive finish that closely resembles that of solid silver.
Solid-state physics is a branch of physics that deals with the study of solid materials, particularly their properties and behaviors at the atomic and molecular level. This field encompasses a wide range of topics, including the structure, dynamics, and interactions of solid materials, with the goal of understanding how these properties arise from the arrangement and behavior of their constituent atoms and molecules.
Superalloys, also known as high-performance alloys, are a class of materials that are designed to withstand extreme conditions, such as high temperatures, high mechanical stress, and corrosive environments. These alloys are primarily used in applications where durability and reliability are crucial, such as in the aerospace, power generation, and automotive industries.
Centerless grinding is a manufacturing process used to grind cylindrical parts without the need for a central axis. Unlike traditional cylindrical grinding, where the part is held between centers, centerless grinding allows for continuous production of cylindrical components by utilizing a system of rollers and grinding wheels. ### Key Components: 1. **Grinding Wheel**: The primary abrasive wheel that removes material from the workpiece. 2. **Regulating Wheel**: A second wheel that controls the rotation and axial movement of the workpiece.
The City Blacksmith Shop typically refers to a business or workshop where blacksmithing—a metalworking process that involves heating and hammering iron or steel to create items—takes place. In a historical context, such workshops were essential in towns and cities, providing tools, horseshoes, weapons, and various metal goods.
The history of metallurgy in Mosul, a city in northern Iraq, is closely tied to the region's rich cultural and economic heritage, which dates back to ancient Mesopotamia. Here’s a summary of its historical context: ### Ancient History 1. **Mesopotamian Origins**: Mosul is located near the ancient sites of Nineveh and Assyria. The region was one of the earliest areas to develop metallurgy, with evidence of copper and bronze working dating back thousands of years.
Electropolishing is an electrochemical process used to remove material from the surface of a metal workpiece, resulting in a smoother, shinier, and more corrosion-resistant surface. This technique is often applied to stainless steel and other metals, enhancing their physical and aesthetic properties. The process involves immersing the metal in an electrolytic solution and applying a positive electrical charge to the workpiece. The surface material dissolves preferentially, smoothing out rough areas and removing contaminants, such as oxides and dirt.
Mass finishing refers to a group of processes used to improve the surface finish of multiple parts simultaneously. This method is commonly used in manufacturing and metalworking to deburr, polish, clean, or improve the surface texture of components. Mass finishing processes can efficiently treat large batches of parts, making them cost-effective for high-volume production.
Model Engineers' Workshop is a magazine that focuses on the interests and activities of model engineers, hobbyists, and those involved in the creation and operation of model and miniature machines, tools, and vehicles. It typically features articles, project ideas, technical advice, and tips for building and improving model engineering projects. The content often includes detailed plans, reviews of tools and equipment, and contributions from readers sharing their experiences and projects.
Peening is a mechanical process used to improve the properties of materials, primarily metals, through the application of a mechanical impact, which induces compressive stresses on the material's surface. This process enhances the material's fatigue resistance, increases hardness, and can help prevent cracking.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
