研究了高钼含量TB8钛合金新型VAR熔炼工艺,采用工业纯钼粉直接加入的工艺方法熔炼生产TB8钛合金铸锭,通过选用合适的原材料和合理的VAR工艺参数,成功的生产出TB8钛合金铸锭。经过不同部位成分分析、低倍金相观察、X射线试验,证明其成分均匀且不存在高熔点、高密度钼组元等夹杂、偏析缺陷。该新型工艺的原料成本、质量成本、生产成本都大幅低于传统工艺。 The new type of VAR smelting process of TB8 titanium alloy with high molybdenum content was studied. The TB8 titanium alloy ingot was produced by the process of directly adding industrial pure molybdenum powder, and the TB8 titanium alloy was successfully produced by selecting suitable raw materials and reasonable VAR process parameters. Ingot After different parts of the composition analysis, low-power metallographic observation, X-ray test, to prove its composition is uniform and does not exist high melting point, high density molybdenum component inclusions, segregation defects. The new process of raw material costs, quality costs, production costs are substantially lower than the traditional process.
