With the ageing temperature rising, the particles are becoming coarsing. 随时效温度升高,粒子粗化。
A study on the coarsing grain entropy and the microscopic entropy in the representation of an inner time operator 内时间算子表象中的微观熵和粗粒熵
To prevent toughness decreasing resulted from crystal coarsing in the partially-melted zone, controlling weld heat input ( E ≤ 20kJ/ cm) is very important during welding. 为防止半熔化区晶粒粗化导致该区域韧性下降,焊接过程中控制焊接线能量(E)在20kJ/cm以下是非常重要的。
With increasing of temperature and deformation amount and deformation time, collective recrystallization will occur, recrystallization α phase will merge and grow up into irregular big strip, causing obvious coarsing of microstructure and increasing of the undulation of fracture surface. 随着变形温度提高、变形量增大和变形时间加长,将发生聚集再结晶,使再结晶α相合并长大成不规则的大片状,引起显微组织明显粗化,断口表面起伏增加。
Effect of Chemical Coarsing Prior to Plating on Plastic on the Surface Structure of the Plastics and Its Coating Adhesion 化学粗化对塑料表面镀层结合力的影响
It was found that double-quenching promotes the appearance of mix-crystal grains and ultra-high temperature double-quenching results in coarsing of austenite grains and producing the inheritance of coarse grain and reduce impact ductile. 发现双重淬火促进混晶出现和超高温双重淬火引起第二次淬火时的奥氏体晶粒粗化和产生粗大晶粒的遗传,从而使其冲击韧性下降。
One of the important factors which affects the adhesion between plastics and its coating adhesion would be the chemical coarsing. 化学粗化是影响塑料与镀层结合力最重要的因素之一。
High purity Mg-3 Al alloy was first inoculated by rare earth elements ( Ce, Y), grain coarsing happened. 先在高纯Mg-3Al合金中加入稀土元素(Ce,Y),发现晶粒粗化。
The optimized process of oil removing, coarsing and electroless copper plating bath are get. 得到了优化的除油、粗化和化学镀铜工艺配方。
