Enhanced high-temperature strength of HfNbTaTiZrV refractory high-entropy alloy via Al2O3 reinforcement
文献摘要：
Novel composites of HfNbTaTiZrV refractory high-entropy alloy(RHEA)reinforced with 0-4 vol.％Al2O3 particles have been synthesized by vacuum arc melting.The microstructure evolution,compressive me-chanical properties at room and elevated temperatures,as well as strengthening mechanism of the com-posites were analyzed.The HfNbTaTiZrV RHEA reinforced with 4 vol.％Al2O3 displayed excellent phase stability at elevated temperatures.A superior compressive yield strength of 2700 MPa at room tempera-ture,1392 MPa at 800℃,and 693 MPa at 1000℃was obtained for this composite.The improved yield strength resulted from multiple strengthening mechanisms caused by Al2O3 addition,including solution strengthening,interstitial strengthening,grain boundary strengthening,and dispersion strengthening.Be-sides,the effects of interstitial strengthening increased with temperature and was the main strengthen-ing mechanism at elevated temperatures.These findings not only promote the development of oxide-reinforced RHEAs for challenging engineering applications but also provide guidelines for the design of light refractory materials with multiple strengthening mechanisms.
