前言 镍钼铁电热合金,是以镍为基,添加26～29％钼,5—7％铁的奥氏体固溶强化型合金。该合金易加工硬化,但亦可选用适当的热处理。 镍钼铁合金,最初是作为抗腐蚀的合金发展起来的。由于合金含有较高的钼,起到非常有效的固溶强化作用,并提高了合金的工作温度。在氧化性气氛中,合金的工作温度可达760℃,在还原性气氛中,使用温度可达900℃。 近年来随着电子工业的发展,镍钼铁合金作为电真空器件用电热合金得到了新的应用和发展。本文从电真空器件用镍钼铁电热合金的角度,对镍钼铁合金的性能进行了研
Preface Nickel molybdenum ferroelectric alloy, based on nickel, added 26 ~ 29% molybdenum, 5-7% iron austenitic solid solution strengthening alloy. The alloy easy to work hardening, but also choose the appropriate heat treatment. Nickel-molybdenum-iron alloy, originally developed as a corrosion-resistant alloy. As the alloy contains a higher molybdenum, played a very effective role of solid solution strengthening and improve the alloy’s working temperature. In an oxidizing atmosphere, the working temperature of the alloy can reach 760 ° C, and in a reducing atmosphere, the operating temperature can reach 900 ° C. In recent years, with the development of the electronics industry, nickel-molybdenum ferro-alloys have been newly applied and developed as electric heat-accumulating alloys for electric vacuum devices. In this paper, from the point of view of nickel-molybdenum ferroelectric alloy for vacuum devices, the properties of nickel-molybdenum ferroalloy were studied.
