Martensite

1) Martensite is the hardest and most brittle microstructure obtainable in a given steel. 2) Martensite hardness of the steel is a function of the carbon content in that steel. 3) Martensite results from cooling from austenitic temperatures rapidly by pulling the heat out using a liquid quenchant before pearlite can form. 4) As quenched Martensitic structures are too brittle for economic use-they must be tempered. 5) Reheating as quenched Martensite to a temperature just below the AC1 results in the best combinations of strength and toughness. This is what you get when you cool faster than the critical cooling (pearlite transition) rate- Martensite Hardness of martensite is a function of carbon content Softening of martensite in 0.35%C, 0.8% C, and 1.2% C carbon steels by tempering at the indicated temperature for 1 hour. Because Martensite transformation is almost instantaneous, the Martensite has the identical composition of the parent phase, unlike ferrite and pearlite which result from a slower chemical diffusion process, so each have different chemical compositions than the parent austenite. Formation of Martensite involves a transformation from a body-centered cubic structure to body-centered tetragonal structure. The large increase in volume that results creates a highly stressed structure. This is why Martensite has a higher hardness than Austenite for the exact same chemistry… Photo and Graphs Credit: Cold Finished Steel Bar Handbook
