Results from a metallographic study of the microstructure of 1.2080 tool steel with and without modifying additions of silicon nitride (Si 3 N 4), after various applied heat treatments are obtained. Distribution of the phases (ledebur eutectic, alloyed martensite, retained austenite and dispersed carbides) and hardness in samples from 1.2080 steel after applied 35% plastic deformation and modifying with silicon nitride have been observed.fatcat:23gxmklfrrbjfpje3xf4rkxdky
