| Description
| - Two high manganese alloys marked A (24Mn-1.2C-12Al) and B (28Mn-0.7C-8.6Al) were laboratory hot rolled. After rolling in the A alloy coarser k-carbides (up to 1 m in diameter) were detected, sporadically on the austenite grains boundaries and more frequently on the ferrite ones. Reason was un-balanced Mn a C contents in superposition with the rolling deformations and finishing rolling temperature of 950°C. The hardness corresponded to 432HV30 on average. Using light microscope no carbides on grains boundaries were observed in the B alloy both after rolling and after aging at 500°C/6 minutes. After 6 minutes aging of the B alloy the hardness was by 9.2 % higher in comparison with the rolled state. The X-ray analysis nucleation of nano-size k-carbides confirmed. After aging of the B alloy at 500°C/30 and/or 60 minutes some coarser k-carbides were detected on ferrite-austenite boundaries and/or austenite-austenite interface. The hardness went up and corresponded to 343 and/or 350HV30. From the X-ray and microstructure analyses follows the 30 and 60 minutes dwell supported both very fine and coarser k-carbides precipitation. The calculated stacking fault energies of both materials complete all solution. The A alloy showed by 9 mJ.m-2 higher stacking fault energy than the B alloy. In the A alloy the lower manganese content and higher aluminium one resulted to 2.8 times higher ferrite volume fraction in comparison with the B alloy.
