Abstract:

In the present work, mechanical properties and microstructures of hot-rolled and solution-treated Fe-26Mn-6Al-1C steel (6Al steel) were investigated. Tensile tests were carried out at room temperature. The samples were characterized by using XRD, OM, SEM and TEM. The results suggested that the microstructure of the hot rolled 6Al steel was fully austenitic. After solution treatment and deformation, the microstructure was still single austenite. With the increase of the solution treatment temperatures, the strength decreased and the elongation increased. After solution treated at 1100°C for 1h, the yield strength, ultimate tensile strength and elongation were 378MPa, 756MPa and 57%.
