中文摘要:研究了时效处理对2205双相不锈钢性能的影响。结果表明:2205双相不锈钢在475 ℃进行时效处理会发生严重脆化现象;其原因是由于在时效处理过程中,δ-铁素体相的微观结构发生了剧烈的转变,从而造成了严重的时效硬化。
英文摘要:The influences of aging treatment on the microstructure and mechanical properties of 2205 duplex stainless steel were studied. The results show that the severe embrittlement occurs in the 2205 duplex stainless steel after aging at 475℃. The cause of the embrittlement is the dislocation structures in the aged δ-ferrite during the aging treatment.
