Design of as cast austenitic stainless steels with TRIP-effect (A02)

在A2耐腐蚀，亚稳部分奥氏体Cr-Mn-Ni铸钢的应变诱导塑性的研究和提供新的钢-陶瓷复合材料的制造。固相研究的目的是将马氏体引入具有TRIP/TWIP效应的间隙强化钢中。此外，还将研究特殊回火处理对合金力学性能的影响。在液相热物理性质的研究中，实验研究了液态Cr-Mn-Ni钢的密度、表面张力和粘度。选定的Fe-Cr-Mn-Ni合金将采用真空惰性气体雾化。

In A2 corrosion-resistant, metastable partially austenitic Cr-Mn-Ni cast steels with strain-induced plasticity will be investigated and provided for the manufacturing of novel steel-ceramic composites. The research in the solid state aims to introduce martensite into the interstitially-strengthened steels with TRIP/TWIP effect. Furthermore, the effect of specially designed tempering treatments on the mechanical properties will be studied. Within the investigation of thermophysical properties of the liquid phase the density, the surface tension and the viscosity of liquid Cr-Mn-Ni steels will be experimentally studied. Selected Fe-Cr-Mn-Ni alloys will be gas atomized using vacuum inert gas atomization.
