摘要
采用不同固溶温度对2205双相不锈钢试样进行热处理,研究固溶温度对钢组织、摩擦磨损性能的影响。结果表明:随着固溶温度的升高,2205双相不锈钢中奥氏体相的形态逐渐由纤维状的条状变为短棒状和岛状,分布更加均匀;另外,铁素体含量随固溶温度的升高而增加,1160℃固溶处理后达到56.3%。在1000〜1160℃,2205双相不锈钢与氮化硅球的摩擦系数曲线具有相似的特性。
Samples of 2205 dual-phase steel were heat-treated at different solution temperatures and the effects of solution temperature on the microstructure,friction and wear properties of the steel were studied.Results show that as the solution temperature increases,the morphology of the austenite phase in 2205 duplex stainless steel gradually changes from fibrous strips to short rods and islands with more uniform distribution.Additionally,the ferrite content increases with a rise in solution temperature,reaching 56.3%after solution treatment at 1160℃.It is also found that between 1000℃ and 1160℃,the friction coefficient curves of 2205 dual-phase steel and silicon nitride balls have similar characteristics.
