钢铁研究学报(英文版)

The mechanical properties and microstructure of two low carbon high manganese steels with 238% (No1) and 33% (No2) (mass percent) of manganese were investigated. The results showed that No1 steel possesses high strength and high plasticity, and No2 steel has a relatively high strength and extra...
