Formation of coherent BCC/B2 microstructure and mechanical properties of Al-Ti-Zr-Nb-Ta-Cr/Mo light-weight refractory high-entropy alloys
文献摘要：
The present work investigated the formation of coherent body-centered-cubic(BCC)/B2 microstructure in Al-Ti-Zr-Nb-Ta-Cr/Mo refractory high-entropy alloy system,in which three alloys with the composition of Al2Ti6Zr2Nb3Ta2(Cr/Mo)1 were designed.These as-cast alloy ingots were homogenized at 1573 K for 2 h and then aged at different temperatures for 24 h.It is found that the BCC/B2 coherent microstructure with cuboidal BCC nanoprecipitates into the B2 matrix would be formed in 873 K-aged Al2TTi6Zr2Nb3Ta2Cr0.2Mo0.5 alloy with half Cr and half Mo,which is ascribed to a moderate lattice misfit(ε=0.94％)between BCC and B2 phases.It is due to the special coherent microstructure that results in a prominent mechanical property with the highest compressive yield strength(σYs=1314 MPa)and good plasticity among these alloys,while coarse Cr2Ti and Zr5Al3 particles are existed in 873 K-aged alloy with Cr1.After 1073 K aging,all these alloys with Cr1,Cr0.5Mo0.5 and Mo1 consist of BCC,B2 and Zr5Al3,in which BCC/B2 coherent microstructure is destabilized.The strengthening mecha-nism of BCC/B2 coherent microstructure in 873 K-aged alloy with Cr0.5Mo0.5 was also discussed.
