A <materials scientist> studies how composition, structure and processing determine a material's properties. The relevant scales can range from atomic defects and <dislocations> to grains, interfaces and bulk components. For example, changing grain size can alter strength while also changing <ductility> or high-temperature behaviour. <Microscopy>, diffraction, mechanical testing and thermodynamic models provide complementary evidence. The goal is to connect a reproducible structural change to a measured property, rather than merely assigning one fixed property value to a material name.
