【摘要】 针对相比例控制的技术难点,以双相不锈钢0Cr26Ni5Mo2N为基础,通过对铸造0Cr25Ni5Mo2N双相不锈钢进行系列温度固溶处理,研究了固溶温度对铸造双相不锈钢组织的影响。研究结果表明:1)当固溶温度在980～1120℃时,随着固溶温度的提高,0Cr25Ni5Mo2N钢中的铁素体相含量几乎呈直线上升。2)采用980～1120℃进行固溶处理时,铁素体基体上分布的长条状、块状和魏氏组织形态的奥氏体的原有尖角边界逐渐钝化,奥氏体本身分解、球化,弥散分布在铁素体基体上,固溶处理温度越高,奥氏体分解、球化程度越高。更多还原

【Abstract】 The effect of temperature of solution treatment on the microstructure of ZG0Cr26Ni5Mo2N duplex stainless steel was studied in this paper.The results are as follow:1)When the solution temperature between 980 ℃ and 1120 ℃,the content of α ferrite increased with the increase of temperature.2)The boundary of strip and block austenite distributed in the ferrite dissolved,and austenite conglobated and dispersalled in the ferrite matrix as the solution temperature increased.The higher temperature,the higher rate the austenite conglobated and dissolved.更多还原
