xFeCoNiCrTi合金的抗氧化性能及其糖心产精国品免费入口*完整版态的组织和糖心产精国品免费入口*完整版(Oxidation Resistance of AlxFeCoNiCrTi Alloys and Its Microstructure and Hardness in Annealing State)">
The microstructure,phase structure,糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版of as-cast and annealed at different temperatures AlxFeCoNiCrTi(x=0.5,1 and 1.5) high-entropy alloys were investigated by using XRD,SEM,DSC and TG.The results show that,with increasing the 糖心产精国品免费入口*完整版 temperature,Fe2Ti type Laves phase precipitated from Al0.5FeCoNiCrTi and Al1FeCoNiCrTi alloys annealed at 785 ℃.The morphology of fcc and bcc2 phases in the alloys had no transformation,but the grains grew up.The microstructure of Al1.5FeCoNiCrTi alloy was stable,and was as-cast microstructure.The 糖心产精国品免费入口*完整版 of as-cast and annealed alloys was about 60 HRC and exhibited extreme tempering resistance and possess application value under high temperature condition.The alloys had excellent performance in oxidation resistance,and that of Al0.5FeCoNiCrTi was the best.
