Interpretation Introduction

Interpretation:

The microstructure obtained for 1080 steel & 4340 steel after quenching needs to be determined, if low alloy 0.2%C steel is used.

Concept Introduction:

Different types of microstructure are ferrite, pearlite, bainite & martensite forms after quenching. Quenching is the heat process in which rapid cooling of material takes place by using cooling fluids such as water, oil. Quenching stops undesired low-temperature process that is phase transformation where quenching is used to harden by introducing martensite.
