Abstract

The Fe–17Mn austenitic manganese steel and its in situ composite containing 10 vol.-%TiC were produced by conventional melting and casting technique. The mechanical properties such as hardness, impact toughness, elastic modulus, and impact wear resistance of the steel and composite were evaluated both in the as solutionised (1100°C/1 h/WQ) and secondary processed (forged plus warm rolled) condition. It is observed that an incorporation of hard TiC particles in austenitic manganese steel as well as secondary processing help to increase the hardness, elastic modulus and impact wear resistance, but deteriorate the impact toughness.

On a produit l’acier austénitique au manganèse, Fe–17Mn et son composite in-situ contenant 10% en volume de TiC, par une technique conventionnelle de fusion et de moulage. On a évalué les propriétés mécaniques comme la dureté, la résistance à l’impact, le module d’élasticité et la résistance à l’usure par impact de l’acier et de son composite après traitement de mise en solution (1100°C/1 h/trempé à l’eau) ou après traitement secondaire (forgé et laminé à chaud). On a observé qu’une incorporation de particules dures de TiC dans l’acier austénitique au manganèse, ainsi que le traitement secondaire, augmentait la dureté, le module d’élasticité et la résistance à l’usure par impact, mais détériorait la résistance à l’impact.
