Marquenching意思

"Marquenching" is a term used in metallurgy, specifically in the heat treatment of steel. It refers to a process where steel is rapidly cooled from an austenitic state to a martensitic state, resulting in a hardened and tempered steel. The term "marquenching" is a combination of the words "martensite" and "quenching."

The process involves heating the steel to a temperature above the critical transformation point, holding it at that temperature for a certain period, and then cooling it rapidly in water, oil, or another quenching medium. This rapid cooling causes the steel to transform into a martensitic structure, which is known for its hardness and strength.

Marquenching is often used on high-carbon and low-alloy steels, such as those used in cutting tools, knives, and other high-wear applications where hardness and wear resistance are critical properties. The process can improve the mechanical properties of the steel, such as increasing its hardness, strength, and wear resistance, while also reducing its brittleness.
