【 摘 要 】

Stacking fault energy of high manganese alloys (marked as TWIP and TRIPLEX) is an important parameter determining deformation mechanism type realized in above mentioned alloys. Stacking fault energy level can be asserted with a) gliding of partial and/or full dislocations, b) gliding mechanism and twinning deformation process in connection with increasing of fracture deformation level (deformation elongation) and with increasing of simultaneously realized work hardening proces., c) gliding mechanism and deformation induced e-martensite formation. In contribution calculated stacking fault energies are presented for various chemical compositions of high manganese alloys. Stacking fault energy dependences on manganese, carbon, iron and alluminium contents are presented. Results are confronted with some accessible papers.The aim of work is to deepen knowledge of presented data. The TWIP and TRIPLEX alloys can be held for promissing new automotive materials.
