Sem analyses of microstructure and effect of annealing on crystallization of boundary glass of ztm composites obtained by reaction - sinter 陶瓷显微结构分析及热处理对晶界玻璃相析晶的影响
There is non - equilibrium grain boundary segregation of sn during continuous cooling and the quantity is different with different cooling rate 当冷却速率低于或高于10 s时， sn的晶界偏聚量减少，热塑性升高。
Among them , 3 plates always lies in the grain boundaries . following the initial region , single p phase region and in2tes phase region are formed in order 在晶锭末端形成in _ 2te _ 3单相区，该相区晶界处有te夹杂相。
This etchant can show different defects , such as dislocations , grain boundaries , twins , te - rich inclusions and precipitates etc . , on different planes 这种腐蚀剂能显示不同晶面上的多种缺陷，如位错、晶界、富te相等。
Embrittled grain boundaries results in the increase of crack growth rates at 425 . ( 2 ) there is little oxidation in 316l at high temperature 试验温度425时晶界氧化脆化起主导作用，疲劳裂纹沿晶界扩展，扩展速率提高。
Excessive imperfections even sub - grained boundaries may be introduced in cementite . this makes the accelerating dissolution and spheroidization of cementite easy . 5 由于渗碳体的强烈塑性变形，在其内部导入了大量的晶体缺陷甚至亚晶界。
Therefore , the strenthening mechanism of rare earth is dispersive atrenthening . the particles exist not only on the boundaries but also in the grains 稀土氧化物颗粒不仅存在于晶界上，也存在于晶粒内部，晶粒内部的稀土颗粒粒径比晶界上的颗粒小。
For srtio3 - based double function ceramic , it is well know that the suitable grain size , the semiconducting of grain and the insulating of grain boundary are important keys 在srtio _ 3基双功能陶瓷的制备中，最关键的是晶粒生长、晶粒半导化和晶界绝缘化。
The grain - boundary cracks are found when the deformation of the strip is greater than a value , and these cracks will become marco cracks with the increase of the deformation 变形量过大时，冷轧薄带内部出现微观晶界裂纹，并随着变形量的增加最终发展成宏观裂纹。
Effects of grain boundaries on the resistivity , capacitance of copper wires and the fuzzy degree of signal transmission have been studied in the present paper 摘要通过分析晶界对铜线材电阻率、电容值以及信号失真度的影响规律，研究晶界对线材传输信号影响的机制。
