5. Conclusions
- The phase transformation of TixZr2.5-xTa (x = 0, 0.5, 1.0, 1.5, 2.0) nonequal-ratio ternary alloys depends not on the value of ΔSmix, but on the amount of Ti atoms. The Zr2.5Ta alloy is characterized by a BCC + HCP dual phase structure. With the introduction of Ti, the content of the HCP phase decreases gradually.
- The degree of component segregation becomes increasingly developed as x increases from 0 to 1.5 and then gradually disappears as x further increases to 2.0, which is closely related to the relative content of Ti-Ta. As the Ti/(Ti + Ta) ratio increases from 0 to 66.6 at%, the dendrite morphology and component segregation of TixZr2.5-xTa alloys first increasingly develop and then gradually disappear.
- With the addition of Ti, the yield strength first decreases and then increases. However, the trends of compressive strength and fracture strain are completely opposite. When x increases to 2.0, the Ti2.0Zr0.5Ta alloy with a single BCC phase and equiaxed grains shows the best mechanical properties, and its yield strength, compressive strength and fracture strain reach 883 MPa, 1568 MPa and 34.58%, respectively.
