MICROSTRUCTURAL MAPPING OF THE AUSTENITIC MANGANESE STEEL-3401 IN RAPID COOLING PROCESS

Riski Elpari Siregar, Reza Fadhila

Abstract


Hadfield's austenitic manganese steel which contained approximately 1.2% carbon and 12 tol4% Mn
is still commonly used for railroad components such as frogs and crossings and also for rock-handling
materials. This paper presents the microstructural development of the austenitic manganese steel-340 I
due to different heating regimes followed by rapid cooling process. The material is heated to l 050°C
followed by a rapid cooling process which caused the solid solution of the carbides to be precipitated
in the grain of the pure austenite phase. The tempering temperature is set between 400°C to 600°C at
50° C interval. The microstructural examination of the samples showed that the formation of austenite
begins by precipitation of iron and manganese carbides at the grain boundaries, progressively followed
by the appearance of a new constituent which later extended to the interior of the grains. The new
phase formation increased with increasing temperature, showing temperature dependence of formation.
