藍(lán)寶石超硬玻璃內(nèi)應(yīng)力的產(chǎn)生主要源于三個(gè)方面：熱應(yīng)力、相變應(yīng)力和機(jī)械應(yīng)力。熱應(yīng)力是由于材料在冷卻過(guò)程中溫度梯度引起的；相變應(yīng)力是由于晶體結(jié)構(gòu)變化導(dǎo)致的體積變化；機(jī)械應(yīng)力則來(lái)自于加工過(guò)程中的外力作用。這些內(nèi)應(yīng)力如果不及時(shí)消除，會(huì)導(dǎo)致藍(lán)寶石玻璃的機(jī)械強(qiáng)度降低、光學(xué)性能變差，甚至在使用過(guò)程中發(fā)生破裂。在工業(yè)生產(chǎn)中，常用的內(nèi)應(yīng)力……
