Heat treatment can change which properties of materials?
Understand the Problem
The question is asking about the effects of heat treatment on the properties of materials. Heat treatment involves controlled heating and cooling processes to alter the microstructure of a material, which in turn affects its mechanical properties. Therefore you should select the options that can be influenced by changes in a material's microstructure.
Answer
Heat treatment can change a material's strength, hardness, ductility, toughness, wear resistance, elasticity, and magnetism.
Heat treatment can change a material's strength, hardness, ductility, toughness, wear resistance, elasticity, and magnetism. It modifies the microstructure of metals and alloys, improving their mechanical properties.
Answer for screen readers
Heat treatment can change a material's strength, hardness, ductility, toughness, wear resistance, elasticity, and magnetism. It modifies the microstructure of metals and alloys, improving their mechanical properties.
More Information
Heat treatment is a process that uses controlled heating and cooling to modify the crystalline structure of metals and metal alloys.
Tips
A common mistake is thinking heat treatment only hardens materials. It can also soften them (annealing) or increase ductility.
