Abstract AITranslate

Ti-1100 alloys with varying Yb2O3contents were prepared by melting-casting method.The mi-crostructural evolution of the alloys were observed by field emission scanning electron microscopy,and the mechanical properties were analyzed through isothermal compression tests conducted on an electronic uni-versal testing machine.The results indicate that the addition of Yb2O3can significantly reduce the grain size of Ti-1100 alloy,the spacing betweenα-lamellae in the grains is smaller,and the distribution ofαla-mellae is denser.With the increase of Yb2O3content,the grain size of the alloy decreases first and then in-creases,and the strength initially increases before decreasing.When the Yb2O3content reaches 0.45%,the alloy exhibits the minimum grain size and maximum strength.
