Deformation Characteristics And Work-Hardening Behaviour Of Some High Strength Manganese Steels.

Abstract

A Study Has Been Made On A New Type Of Wear

Resistant/High Strength Iron-Manganse-Molybdenum Steel. This

Study Includes The Influence Of Composition And Heat Treatment

On The Mechanical Properties. The Exceptional Work-Hardening

Rate Is Due To Strain-Induced Formation Of Lath Martensite

Which Itself Also Takes Part In The Work-Hardening Process.

The Influence Of Higher Molybdenum Contents Was Evident In

Preventing Brittleness Of The Solution Treated Steels. An

Optimum Composition Range For This Type Of Steel Is Indicated.
