采用差分方程的淬火冷却曲线的近似解法——时弘义雄等,《热处理》22,1982,1,2～8(日)用热传导方程式求淬火冷却曲线时,其热放散比(h),随淬火液的种类、温度和淬火试样的形状、尺寸和材质而变化。为求出淬火试样心部的近似冷却曲线,将热传导方程式进行差分计算,这样可以认为,h 不受试样形状、尺寸及冷却介质温度的影响,对各种淬火液,其 h 仅为试样温度的函数。由 Approximate Solution of Quench Cooling Curves with Difference Equations - Shihong Hong et al., Heat Treatment 22, 1982, 1, 2-8 (day) When using the heat conduction equation for the quench cooling curve, the heat dissipation ratio With the type of quenching fluid, temperature and quenching the sample shape, size and material changes. To obtain the approximate cooling curve of the quenched sample heart, differential calculation of the heat conduction equation, so that h is not affected by the shape of the sample, size and cooling medium temperature, for a variety of quenching fluid, h only test A function of the temperature. by
