摘要
针对工程需要研制了一种电阻率≥1.5μΩm的NiMoCrAlSiTi高电阻合金,因合金的加工性能较差,为了加工成材,对加工工艺进行了系统研究。采用热模拟压缩方法绘制了热加工图,进而确定了热开坯方法及工艺参数;采取多次压缩、分段降温方法模拟了热轧过程,确定了热轧工艺参数;通过调整道次压下量,火次压下量以及轧辊直径与板厚的匹配,轧制出了厚度0.01 mm公差≤±0.001 mm的箔材,各项性能指标达到协议要求。
In order to meet the engineering project needs,a nickel-based alloy NiMoCrAlSiTi whose resistivity is higher than 1.5 μΩ·m was studied.Because of the poor workability,the processing technique of the alloy was researched.Through the hot compression experiment,the processing maps were established,the cogging method and the processing parameters were determined.Using the method of repetitious compress and stepped cooling to simulate the hot rolling process,the hot rolling processing parameters were confirmed.By adjusting the working rate of every pass and every heating,adjusting the diameter of roller and the thickness of the strip in order to match each other,the foil with 0.01 mm thickness,tolerance not beyond ±0.001mm was finally rolled,which has a good performance and meet the contract requirement.
