High strength steels form the backbone of infrastructure in Canadian economy. Two mechanical properties important for their application are strength and ductility. In recent years, there have been significant interest in improving these properties via addition on manganese (Mn), leading to the so-called twinning-induced plasticity (TWIP) steels. International steel companies such as POSCO have developed and manufactured high Mn steels with excellent formability characteristics; however their manufacturing process is very expensive. To overcome this, Hatch Ltd., a Canadian company, has developed new processes for cost-effective production of high-Mn steel (~17 wt% Mn) and intermediate-Mn steel (~6 wt% Mn), pending US patents. The mechanical properties of steels manufactured by Hatch technology have not been studied yet. Furthermore, an

高强度钢材构成了加拿大经济基础设施的支柱。对于其应用来说重要的两个机械性能是强度和延展性。近年来，人们对通过添加锰 (Mn) 来改善这些性能产生了浓厚的兴趣，从而产生了所谓的孪生诱导塑性 (TWIP) 钢。 POSCO等国际钢铁公司开发并制造了具有优异成形性能的高锰钢；然而，它们的制造过程非常昂贵。为了克服这一问题，加拿大公司 Hatch Ltd. 开发了一种经济高效的高锰钢（约 17 wt% Mn）和中锰钢（约 6 wt% Mn）生产新工艺，正在申请美国专利。采用 Hatch 技术生产的钢材的机械性能尚未得到研究。此外，一个
