本试验是在实验室的条件下进行的,对恒弹性合金(Ni-SpanC)的真空感应熔炼工艺作了研究,并着重于合金化学成份的控制方面。为了进一步降低合金的含氮量,在热力学和动力学计算的推导下,也作了一些脱氮的研究。一、脱气的热力学和动力学计算本合金是在2.6×10~(-7)大气压下真空感应冶炼的。合金的最终成份如下: 元素 Ni Cr Ti Al Mn Si Fe ％ 41.8 5.2 2.6 0.6 0.6 0.5 余量我们采用了二种不同的装料方法进行冶炼:一种是Fe
The experiment was conducted under the laboratory conditions, the constant-elastic alloy (Ni-SpanC) vacuum induction melting process has been studied, and focuses on the chemical composition of the alloy control. In order to further reduce the nitrogen content of the alloy, some studies on denitrification have also been made under the derivation of thermodynamic and kinetic calculations. First, the degassing thermodynamic and kinetic calculations The alloy is vacuum induction smelting 2.6 × 10 ~ (-7) atmospheric pressure. The final composition of the alloy is as follows: Element Ni Cr Ti Al Mn Si Fe% 41.8 5.2 2.6 0.6 0.6 0.5 balance We used two different charging methods for smelting: one is Fe
