含有1．9-2．5％Re,0．4-0．6％Ti的键镍钛合金是一种具有很好综合性能的高弹性材料,属于时效硬化型合金,用于航空仪表中制造动压膜盒时,对材料的成型性能,机械、弹性性能,以及尺寸精度、表面质量等,都有较严格的要求。文中对本厂生产的铍镍钛合金带材试制工作加以总结,并探讨合理的生产工艺,其生产工艺特点如下：1．铸锭在1000-1050℃、温度下以每道次5％左右的加工率直接进行热轧开坯；2．中间热处理采取在800-900℃温度下真空退火；3．最终热处理在有效加热区长度不短于3 m的连续淬火炉中进行,其工艺参数为：温度1050℃,带材通过速度：2 m／min。带材在淬火状态下杯突值不小于7mm (冲头半径10mm),具有良好的成型性能；时效处理后具有很好的件能：抗拉强度σb为160-180kgf／mm2,硬度Hv为550kgf／mm2左右,弹性模量E为18000-20000kgf／mm2,弹性后值不大于0．3％。
Key nickel-titanium alloy containing 1.9-2.5% Re, 0.4-0.6% Ti is a highly elastic material with good overall properties and is age hardenable alloy for use in aviation instrumentation Dynamic pressure capsule, the material forming properties, mechanical, elastic properties, and dimensional accuracy, surface quality, etc., have more stringent requirements. In this paper, the factory production of beryllium nickel titanium alloy strip trial work to sum up and explore the reasonable production process, the production process features are as follows: 1. Ingot at 1000-1050 ℃, the temperature at a rate of about 5% per pass direct hot rolling billet; Intermediate heat treatment taken at 800-900 ℃ vacuum annealing temperature; The final heat treatment in the effective heating zone length of not less than 3 m continuous quenching furnace, the process parameters: temperature 1050 ℃, the strip through the speed: 2 m / min. Tape in the quenching state cup protruding value of not less than 7mm (punch radius of 10mm), with good formability; aging treatment with good pieces of energy: tensile strength σb 160-180kgf / mm2, hardness Hv 550kgf / Mm2 or so, the elastic modulus E is 18000-20000kgf / mm2, the elastic value is not more than 0.3%.
