Nov 21, 2018 In the heat treatment process, the carbide is dissolved in the austenite in a solid solution state, so it is also called solid solution strengthening treatment. The parameters of solid solution treatment of high manganese steel mainly include furnace temperature, heating rate, holding temperature, holding time and placement position

Manganese steels have extensively application in industries due to good resistance to wear, high work hardening capability with high toughness and ductility. Heat treatment is the main process to obtain desired mechanical properties and microstructure in this steel. The austenitizing temperature, the austenitizing time and the rate of quenching are the main factors in heat treatment

Apr 29, 2010 They say that everyone and everything gets 15 minutes of fame somewhere, sometime, somehow. Well, for manganese, its time is now. The effect of a particular alloying element on both the steelmaking process and the steel’s response to heat treatment depends on the individual element and on its (complex) interactions with other elements, either individually or collectively

Aug 10, 2018 A resistance furnace was used for the heat treating process. Hadfield steel usually used after the solution heat treatment at approximately 1000 C to have homogenous austenitic matrix [].Thus, specimens were prepared with the following solution process as the first stage: heating to 620 C and maintaining for 20 min and then austenitized to 1050 C for 20 min, followed by the water quenching
