| Abstract: | A new production route for producing a new class of oxides dispersion strengthened(ODS) steels was investigated.The steel produced by the chemical socking method has high temperature strength,low ductile-to-brittle transition temperature,good creep properties and void swelling resistance.The formation process and behavior of oxides(Y2O3) in the prealloyed powders were analyzed in the process of thermal decomposition,interfacial reactions of hot isostatic pressing,and precipitation of deformation processing.... |
