A company, which makes forging die wants to improve their steel parts and they contacted you because they heard you know a technology using martensitic transformation to make the surface of their steel product hard. The company selected AISI 1008 steel for their product, but after heat treatment they have no idea how to verify whether the heat treatment did a sufficient job or not.
a. What test will tell whether the heat treatment was good enough?
b. If you have hardness test among the potential testing methods in the list what kind of hardness tests are available and what specific hardness test are you going to suggest to the company? And why?
c. After suggesting the methodology to the company, the company engineer came back with a very low hardness value. What went wrong?
d. What is the solution you want to provide to the company and why?
