heat treatment. Moreover, the mechanical properties of high manganese steels are very dependent on carbon and manganese contents [21]. These two elements play an essential role in promoting precipitation strengthening and therefore strongly influence the mechanical properties such as tensile properties, impact toughness, and wear resistance [22].

12%Since the carbon content ≥ 1.30% in a high-manganese steel is quite close to its ultimate solubility in the austenite, we should expect that in conventional modes of heat treatment of this steel the probability of formation of residual carbides in the austenite structure will be the greater the higher the carbon content in the casting.

The typical heat treatment cycle for the Hadfield manganese steels consists of a solution anneal followed by a water quench. This cycle can start off at room temperature or at an elevated temperature depending on the starting temperature of the castings.

steel - steel - Effects of heat-treating: Adjusting the carbon content is the simplest way to change the mechanical properties of steel. Additional changes are made possible by heat-treating—for instance, by accelerating the rate of cooling through the austenite-to-ferrite transformation point, shown by the P-S-K line in the figure. (This transformation is also called the Ar1 transformation ...

Hadfield's austenitic manganese steels are best described as retained austenites. Steels heat-sensitized at 400 – 800°C range, such as slowly cooled castings, develop intergranular embrittlement caused by hypereutectoid carbide precipitation. A solution annealing and water quenching heat treatment restores the mechanical properties.

Since the carbon content ≥ 1.30% in a high-manganese steel is quite close to its ultimate solubility in the austenite, we should expect that in conventional modes of heat treatment of this steel the probability of formation of residual carbides in the austenite structure will be the greater the higher the carbon content in the casting.

ADVERTISEMENTS: The first step in the true heat treatment cycle of steel is the austenitisation, i.e. to get a homogeneous austenite by heating it to a predetermined temperature in the austenite stability range. Normally, the initial structure of carbon steels, before this heat treatment, is ferrite + pearlite (in hypo-eutectoid steels), pearlite (eutectoid steel), or […]
