An annealing process of the 20 carat dental gold alloy was studied by hardness testing, electrical resistivity measurement and optical microscopic observation. The material was cold rolled to 67.4% and 90.7% in reduction and subsequently annealed in the temperature range from 300 degrees to 500 degrees C. Microscopic observation, electrical resistivity and hardness testing revealed that the annealing process were three distinguishable stages, recovery, recrystallization and grain boundary migration. Activation energies, the order of the reaction involved, and frequency factors for various annealing processes were established.
通过硬度测试、电阻率测量和光学显微镜观察，对20克拉牙科金合金的退火过程进行了研究。将该材料冷轧至67.4%和90.7%的压下率，随后在300℃至500℃的温度范围内进行退火。显微镜观察、电阻率和硬度测试表明，退火过程分为三个不同阶段：回复、再结晶和晶界迁移。确定了各种退火过程的激活能、反应级数和频率因子。
