摘要: 采用熱壓縮和熱拉伸試驗(yàn)方法,對(duì)00Cr22Ni5Mo3N雙相不銹鋼的高溫變形抗力、高溫塑性以及在高溫變形時(shí)的奧氏體相的數(shù)量進(jìn)行了研究。試驗(yàn)結(jié)果表明,00Cr22Ni5Mo3N雙相不銹鋼的高溫變形抗力和高溫塑性較0Cr18Ni10Ti奧氏體不銹鋼低,在1100～1250℃變形時(shí),鋼中奧氏體相的數(shù)量可以控制在適合熱加工的范圍,使鋼具有較好的熱加工性能。

Abstract: With employment of the thermocompression test and thermal tensile test, the hot workability of the 00Cr22Ni5Mo3N dual phase stainless steel is studied, focusing on the hi-temperature deformation-resistance, hi-temperature plasti city and the quantity of austenitic phases during deformation in high temperature. The result shows that the hi-temperature deformation-resistance and hi-temperature plasticity of the said steel is lower than those of the 0Cr18Ni10Ti austen ite stainless steel, and that during deformation in the temperature range of 1,1 00~1,250 ℃, the quantity of austenitic phases can be controlled to a proper extent for the hot work so as to ensure better hot workability of the said dual phase stainless steel.
