To Study The Formation Of ￡ And A' Martensite In High Manganese Steels Via Deformation And Transformation Mode And Its Correlation With Mechanical Properties
Authors: Dinesh Kumar
Introduction of phases as z and a' martensite in high manganese steel should significantly posses different mechanical properties in steel. In present work five different compositions of high Manganese steels are selected with various carbon (range from 0.1-0.5) content after homozenisation and forging at 1150°C for 4 hours.
