What does the absolute layer thickness depend on?
A
Temperature at which the isothermal transformation is allowed to occur
4
Q
Martensite is a __ single-phase structure that results from?
A

5
Q
Carbon atoms remain as __ in martensite?
A
Interstitial impurities
6
Q
What is an athermal transformation?
A
Transformation that is independent of time and is only a function to which the alloy is quenched
