【摘要】 利用灰色系统理论建立了C3602铅黄铜退火后硬度预测的数学模型,结果显示在250℃～500℃退火温度范围内,预测值与实测值呈现出较高的吻合性,其相对误差在0.99%～2.27%范围之间,C3602铅黄铜冷加工后软化温度为400℃。研究表明灰色理论用于C3602铅黄铜性能预测是可行的。更多还原

【Abstract】 The mathematic model of predicting C3602 leaded brass hardness after annealing was set up with the help of grey system theory.The results show that the predicted values almost matched with the measured values under the annealing temperature from 250℃ to 500℃ and their relative errors were between 0.99% and 2.27%.The softening temperature of cold-worked C3602 leaded brass is 400℃,which indicates that the prediction of properties of C3602 leaded brass with the help of grey theory is feasible.更多还原
