摘　　要：本文研究了＜１１２＞轴向取向Ｔｂ０３１Ｄｙ０６９（Ｆｅ１９５Ｍ００５）１９５（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。The relationship between acoustic velocity and elastic modulus of the <112> grain oriented Tb_0.31Dy_0.69(Fe_1.95M_0.05)_1.95(M=Mn,Al,etc) alloy and applied magnetic field was studiedWith 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
