Research of a Novel Low-Carbon High-Manganese Alloy Containing Boron

Abstract:

In this paper, a novel low-carbon high-manganese alloy containing boron was developed. The results indicate that the microstructure of the as-cast alloy is consist of ferrite matrix (with some residual austenite), M2B boride, M23(C,B)6 and Ti(C,N) phase, and the boride is distributed in the form of intermittent network, which is detrimental to the toughness of the alloy; after high temperature quenching heat treatment, boride was dissolved somehow and the volume fraction of boride was decreased, moreover, it is distributed more even which results in the further improvement of toughness and provisions non-proportional compression stress of the alloy; the effect of heat treatment on microstructure of the alloy was explained by thermodynamics.
