Effect of work-hardening on the relationship between compressive strength and hardness of quenched medium carbon steel

Nihon Kikai Gakkai ronbunshu
Since it is known that tensile strength and hardness are roughly proportional, a hardness test is often used as a simple and substitute test. However, it has been reported that the proportional relationship between tensile strength and hardness is broken
