Dependence of Deformation Twinning on Grain Orientation and Texture Evolution of High Manganese TWIP Steels at Different Deformation Temperatures

FANG Xiu-hui , YANG Ping , LU Fa-yun , MENG Li

钢铁研究学报(英文版)

Mechanical properties, microstructure and texture evolution were studied in two tensile-deformed high manganese TWIP steels at different temperatures. Special attention was paid to the effects of deformation temperature and grain orientation on twinning behavior. The results showed that, at -70 ℃ an...

Microstructure and Impact Wear Resistance of TiN Reinforced High Manganese Steel Matrix

MA You-ping , LI Xiu-lan , WANG Cheng-hui , LU Lu

钢铁研究学报(英文版)

A high-manganese austenitic steel matrix (Mn13) composite reinforced with TiN ceramic particles was synthesized by means of Vacuum-Evaporation Pattern Casting (V-EPC). The composite microstructure and interface bonding of TiN/matrix were analyzed utilizing optical microscope (OM) and X-ray diffracti...
