Investigating the Relationship Between Hardness and Yield Strength of Ss400 Steel Using Nanoindentation

In this study, Nano Hardness test was carried out at room temperature with different strain rates from 0.002 s-1 to 0.2 s-1,. A reverse algorithm was used to determine the yield strength from the load-displacement curve of the indentation test. From the obtained yield strength and hardness at different strain rates, the hardness-yield strength relationship was constructed.
