中文拼音 [róngjiězhōngrè]
溶解終熱
英文
last heat of dissolution-
We apply the system to the ultra - fine grain steel welding, the simulated mean grain size in cghaz agreed well with the corresponding independent experimental data. in this paper, three factors influencing the grain growth, the steep temperature gradient in haz. the grain boundary liquid and the precipitates particle, were studied specially using mc technique
研究表明溫度梯度造成的「熱釘扎」現象和晶界液化現象都對靠近熔合線附近的晶粒長大有明顯的阻礙作用，對最終的晶粒大小分佈有重要的影響：而800mpa超細晶粒鑰中的tin粒子山于溶解溫度高，抑制奧氏體晶粒長大的效果十分顯著。The formation process and mechanism are investigated : the adding of n ( ch2ch2oh ) 3 promoted the dissociation of cf3cooh in the starting solution and some non - volatile, fluorine containing intermediates can be remained after tray - drying of the solution. during the following heat - treatment process, the intermediates decomposed and further react with the rest amorphous calcium phosphate, leading to the final formation of fha or fa phase. the fluorine content in the fha phase obtained could be tailored by the content of cf3cooh added.
發現cf _ 3cooh只有在加入n （ ch _ 2ch _ 2oh ） _ 3的條件下才能形成fha相和fa相，其機理是：在溶液中加入n （ ch _ 2ch _ 2oh ） _ 3能夠促進溶液中cf _ 3cooh的離解，形成無揮發性的含氟過渡化合物，溶液快速乾燥后的中間產物中仍能保留過渡性的含氟化合物，在隨后的熱處理過程中，過渡化合物分解並與非晶態的鈣磷酸鹽反應最終生成fha相或fa相。
