| 摘 要： | 利用冲击大电流电阻加热法，研究了三种合金在不同温升率下的弹塑性热软化性能。发现了这三种合金的屈服强度随温升率提高而明显提高的现象；分析了温升率高低对金属再结晶过程的影响；并提出了弹性热软化的估算公式及屈服温度上下限的概念。

| Abstract: | This paper describes the experiments and theoretical analysis for elasticplastic thermo-softening of three alloy specimens subjected to rapid resistance heating while being hold to constant uniaxial tensile load. It is found that the yield temperature of the three alloy increases markedly as heating rate increases. The relation between heating rates and recrystallization is discussed. An elastic thermo-softening equation is derived to estimate the Young's modulus of metals under high temperature. A concept of upper and lower bounds of yield temperature is proposed forw for any metal under various heating rates. |
