Název v původním jazyce

Microstructural analysis of high manganese alloy

Popis výsledku v původním jazyce

The work deals with microstructural analysis of the high manganese TWIP alloy after four heat treatments (HT). The alloy was cast, homogenized at the 1200°C/4h/water and forged into the final bars with 12 mm in diameter being the start material (A-variant). Further, three followed HT were carried out: 1150°C/3h/air (B-variant), 1150°C/3h/water (C-variant) and 1150°C/3h/water + 550°C/4h/air (D-variant). Micro-hardness HV0.2 showed the highest level in the under surface areas (US) in comparison with the central areas (CA) and after the A-variant. The determined austenite grain size was generally coarser in the CA. The calculated stacking fault energy corresponded to 22.2 mJ.m-2at ambient temperature. The X-ray analysis did not revealed -martensite both in the US and in the CA. The austenite matrix demonstrated TWIP effect. At ambient temperature the tensile tests of the A- and B variant were carried out.
