摘要
Abstract
After solid solution and aging,the samples of K4648 alloy without yttrium and with yttrium addition were prepared by the same process,using two formulations without yttrium and with 0.02%yttrium.Tensile test at room temperature,high temperature endurance test and anti-oxidation test were carried out respectively.The results showed that after adding 0.02%yttrium,the average elongation increased from 9.6%to 14.5%,the average value of impact toughness increased from 21.5 J/cm2 to 24.4 J/cm2,and the sample's durable life increased from 50 h to 60 h.However,it had little effect on the tensile strength at room temperature.关键词
