Reducing the Time of Heat Treatment Cycle of the Manganese Steel

Abstract

Manganese steels (Hadfield) have a wide application/requirement in industries because of their respectable resistance to wear, great hardening capacity for work, as well as high hardness and ductility. The customary heat treatment for these steels is defined as the solution of annealing and cooling in a water bath. This heat treatment has the objective of eliminating carbides and has many costs because it requires a stretched time of operation. Within the current research, 5 different heat treatment cycles have been evaluated to achieve shortest & undeviating possible time with the proper structure without carbide. The microstructure/grained structure & impact energy of samples with different thermal treatments were investigated. The concluded outcomes illustrates that, the best cycle is to austenite at 1080 ° C with a certain maintenance rate and time of 2 hours and then quench in water, so it consume less time & the finishing structure is completely austenite
