中文摘要
为了开发新型轻质高强高耐热镁合金,我们对长周期有序堆积(LPSO)结构含相镁合金进行了基础和前沿研究。含LPSO相的镁合金由于其相抑制孪晶变形,具有较高的强度和合理的塑性等力学性能。此外,在塑性变形过程中,扭结变形发生在LPSO相。本研究阐明了引入扭结变形带对合金的强化作用,揭示了合金元素对LPSO相形成的准则。
英文摘要
In order to develop novel lightweight high strength and highly heat-resistant magnesium alloys, we have performed fundamental and advanced research for long-period stacking ordered (LPSO) structure phase-containing Mg alloys. The LPSO phase-containing Mg alloy exhibits excellent mechanical properties such as high strength and reasonable ductility because LPSO phase suppresses a twin deformation. Furthermore, kink deformation occurs in the LPSO phase during plastic deformation. In this study, we have clarified the alloy strengthening by introduction of kink deformation band, and exhibited the criteria of alloy elements for formation of LPSO phase.
