对耐热弹性合金材料的抗松弛性能、弹性模量、弹簧扭矩进行了重点分析和研究.研究了合金在不同热处理工艺下对松弛率力学性能的影响,以及弹簧扭矩随扭转角度的变化情况.结果表明,研制的弹簧抗松弛性能优于进口产品;弹簧的扭矩性能满足国家重点试验机的要求;在达到扭矩值6.86N·m后回转90°,测得最低扭矩值测得为5.12N·m;普遍回转90°的扭矩值为5.45～5.65N·m.弹型模量温度系数βE计算得出为 3.91×10~(-4)/℃.计算610℃时弹性模量相对室温的变化为:ΔE/E_o=23.78%.
Anti-relaxation property ,elastic modulus,spring torgue are emphasisly studied,in this article about heat-resisting spring alloy.reserch different heat treatment processes affecting anti-relaxation rate,as soon as spring torgue change with turning angle.The results prove the studing spring superior to Imported Products,the torgue meeting need of National-key-machine,affter arriving torque value 6.86N·m,rotating 90 degrees,testing torque value 5.12N·m,in general case,rotating 90 degrees testing torque value from 5.45 to 5.65N·m.Calculated value of the elastic module temperature coefficient is 3.91×10~(-4)/℃.In 610℃,change of elastic modulus relative room temperature isΔE/E_o=23.78%.
