摘要
文章研究了B元素的添加对Ni_(46)-xFe_(18)Ga_(27)Co_(9)B_(x)(at.%,x=0,0.1,0.5)磁致形状记忆合金显微组织、相变温度和力学性能的影响。结果表明:在Ni_(46)-xFe_(18)Ga_(27)Co_(9)B_(x)(at.%,x=0,0.1,0.5)合金中用B元素替代部分Ni元素,合金的抗压强度和塑性同时得到了提高,其相变温度随B含量的增加而降低。常温下各成分合金都为奥氏体相,随着B含量的增加会有弥散相析出。
The effect of B addition on the microstructure,transformation temperatures and mechanical properties of Ni_(46)-xFe_(18)Ga_(27)Co_(9)B_(x)(at.%,x=0,0.1,0.5)magnetic shape memory alloys was investigated.The results show that the substitution of B for Ni in Ni_(46)-xFe_(18)Ga_(27)Co_(9)B_(x)(x=0,0.1,0.5)alloys is proved to be effictive in increasing the compressive strength and ductility.Meanwhile,the martensitic transformation temperatures decreased with increasing B content in these alloys.,all the alloys are austenite phase at room temperature,with the increase of B content,and the dispersion phase precipitates with the increase of B content.
