本文主要介绍Ni42Cr6Al合金的制备工艺和材料应用。本合金的特性,要求严格控制合金的化学成份,对于少量添加元素要求以固溶态形式存在于合金之中。合金的加工性能优异,但对冷加工带材的表面状态提出了一些新的要求。 本合金具有优良的冲制性能,在正确地选择零件的清洗、氧化工艺条件下,所制作的电视显象管具有高的真空气密性,本合金已经进行了批量生产,并通过了国产线制管单位的鉴定,也通过了引进线对材质的阶段认定。
This article describes the Ni42Cr6Al alloy preparation process and material applications. The characteristics of the alloy, strict control of the chemical composition of the alloy, for a small amount of added elements required to form a solid solution in the alloy. Alloy processing performance, but the surface condition of cold-worked strip made some new requirements. The alloy has excellent punching properties, the correct choice of parts cleaning, oxidation process conditions, produced by the TV picture tube with high vacuum tightness, the alloy has been mass-produced, and adopted the domestic line Pipe unit identification, but also adopted the introduction of the stage of the material identified.
