热处理对Tb-Dy-Fe合金声速和弹性模量的影响
The Influence of Heat Treatment on the Acoustic Velocity and Elastic Modulus of Tb-Dy-Fe Alloy
【摘要】 本文研究了<112>轴向取向Tb031Dy069(Fe195M005)195(M=Mn,Al等)合金的声速和弹性模量与外加磁场的关系。随着磁场强度的增加,弹性模量和声速逐渐降低,在10kA/m时达到最小,随后逐渐增加。在950~1080℃热处理3h,在相同磁场下材料的声速和弹性模量达到最低值。
【Abstract】 The relationship between acoustic velocity and elastic modulus of the <112> grain oriented Tb0.31Dy0.69(Fe1.95M0.05)1.95(M=Mn,Al,etc) alloy and applied magnetic field was studiedWith the increase of applied magnetic field intensity,the elastic modulus and acoustic velocity decreased at first and reached the lowest at 10kA/m,then increased gradually.With heat treatment at 950~1080℃ for 3h,the alloy has the optimum acoustic velocity and elastic modulus at the same applied magnetic field
