退火预处理对20Cr-5Al钢氧化膜构造的影响 氧化膜预处理三元催化剂构造退火汽油发动机柴油发动机转换器排气净化摘要:张朝生编译国外金属热处理
Fe-20Cr.5AlStainlessSteel,RareEarthElementLa,La,0,Al,0,ESR,Alloying 通过汽车尾气净化器来净化废气是处理汽车尾 气的最成熟方法,而Fe-20Cr一5A1不锈钢是最适合汽 车尾气净化器载体的材料之一。 目前生产Fe一20Cr一5A1不锈钢主要采用不加稀 土熔炼加工的方式。但是,不加稀土熔炼加工生产 ...
Growth stress and spontaneous deformation in Fe-20Cr-5Al-(0, 0.06)La alloy thin strip oxidized at high temperature have been studied. The spontaneous deformation of the metal substrate was considered as creep behavior. The activation energy for the creep was determined from the relationship between...
将镍、铬、铝粉按比例混合后,再添加不同质量分数(0~5%)Y2 O3粉作为弥散相,采用粉末冶金技术制备了Ni-20Cr-5Al-xY2 O3(质量分数/%)...

If the Fe–20Cr–5Al based alloys are deposited as coatings, for example as a compliant layer onto a stronger substrate, there is a risk that other elements (such as silicon) from the substrate may diffuse through the coating and influence the subsequent oxidation behaviour of the coating. ...
