摘要
通过研究固溶温度和时效温度对Cr20Ni80镍铬合金电热丝硬度、电阻率和线膨胀系数的影响,以确定Cr20Ni80合金的固溶及时效工艺。结果表明,最佳处理工艺为1150℃固溶处理+930℃×10 h时效,电热丝的线膨胀系数明显下降,而电阻率无明显变化。
By studying the influence of solid solution temperature and aging temperature on hardness, resistivity, and linear expansion coefficient of Cr20Ni80 alloy heating wire, solid solution and aging process of Cr20Ni80 alloy were determined. The results show that after solid solution at 1150 ℃ and aged at 930 ℃ for 10 h, the linear expansion coefficient decreases significantly, electrical resistivity no change, hardness decreases slightly.
