耐深低温、高补偿量新型磁温补偿合金1J30M的研制

New Magnetic Temperature Compensation Alloy 1J30M

磁温补偿合金1J30经深低温处理后合金中的部分奥氏体转变为马氏体,致使合金的磁温补偿能力下降。通过调整镍含量,同时添加铬,得到了新型磁温补偿合金1J30M。这种新型磁温补偿合金既具有1J30合金的磁温补偿能力,又具有1J32合金的耐深低温能力。

After cryogenic temperature treatment, the magnetic temperature compensation ability of 1J30 decreased. It was found that part of austenite in 1J30 was transformed to martensite. Adjusting the content of Ni and adding Cr, the new magnetic temperature compensation alloy 1J30M was found. 1J30M had both high magnetic temperature compensation property of 1J30 and cryogenic temperature property of 1J32.
