Study on Microstructure of Zr-1Nb-0.1Fe-0.1Cu Zirconium Alloy AITranslate
Abstract AITranslate
Zr-1 Nb-0.1 Fe-0.1 Cu plate samples with a thickness of 1.4 mm were prepared with sponge zirconium by electrode pressing,vacuum consumable arc melting,forging,homogenization treatment,quenching,hot rolling,multi-pass cold rolling and annealing.The metallographic microstructure of Zr-1 Nb-0.1 Fe-0.1 Cu alloy and the composition,size,structure and distribution of the second phase were analyzed by OM,SEM and TEM.The test results show that the metallographic microstructure of Zr-1 Nb-0.1 Fe-0.1 Cu alloy annealed at 580℃for 2 h is basically recrystallized equiaxed crystal,the grain size grade is 13,and the average grain size is less than 6μm.Elliptical second-phase particles are precipitated and dispersed in the grains and grain boundary of the alloy.More than 95%of the second-phase particles have smaller size than 200 nm.There are three kinds of second-phase particles in Zr-1 Nb-0.1 Fe-0.1 Cu alloy,includingβ-Nb precipitate with a large content,a grain size of less than 100 nm,and bcc structure,(Zr,Nb)2Fe precipitate with a less content,a grain size of less than 200 nm,and hcp structure,and Zr;Cu precipitate with the least content,a greater grain size than 200 nm,and tetragonal structure.
