Difference between hardening and tempering
WebThe ratio between the ε-carbides and ferrous structure is due to a precipitation-hardening effect of martensite in high-C steels that are tempered between 50 and 100 °C. Stage 2 – Tempering at higher temperatures, in the range 200–300 °C for 1 h, induces retained austenite to decompose into a mixture of cementite and ferrite. WebJun 10, 2024 · Tempering generally reduces hardness/strength, but improves toughness. Aging martensite is done for a group of specialty steels; PH-precipitation …
