Concept Introduction:
Material hardness is the property of a metal due to which material resist the plastic reformation. Plastic reformation means material reformation which undergoes non-reversible change. Hardness is the property of any material due to which it resist to bend, scratch or any other deformation. Hardness is not constant or fixed for all material, but it depends upon strength and plasticity of metal, material hardness is expressed in terms of hardness number.
Answer to Problem 13.16P
Heating to
Explanation of Solution
The given diagram is a TTT diagram which gases a relation between composition and temperature with time.
The given image shows temperature and time for ferrite, pearlite, bainite, and martensite following are the steps to obtain appropriate isothermal heat treatment.
For isothermally annealed
