shock resistance test meaning in Chinese
耐碰撞试验
Examples
- Changing the grading of sic particles not only affects the strength and pile density , but also modifies the phase compositions and microstructure of the material . with the reducing of sic particles , the strength of the material increases obviously . the nitrification scheme has the greatest influence on phase compositions and microstructure " of si3n4 ( si2on2 ) - sic , after two continuous nitrification reacting peak and short - time high - temperature treating , the best properties can be obtained ; and the residual strength of the composite is much higher after the thermal shock resistance test , which shows that the material possesses excellent thermal shock resistance
本论文较全面地探讨促进强度和显微结构良好的si _ 3n _ 4 ( si _ 2on _ 2 )结合相的实验条件，实验数据显示：引入适量的烧结助剂能够促进si _ 3n _ 4 ( si _ 2on _ 2 )的生成和晶粒的长大，而过量时，其促进作用反而下降；随着si粉加入量增加，生成的结合相明显增多，复合材料的性能显著提高；改变sic颗粒级配不仅影响复合材料的强度与堆积密度，而且对复合材料的物相与显微结构也有影响，随着颗粒逐渐细化，材料的强度有较大的提高；对复合材料的强度、物相与显微结构影响最大的是氮化制度，经过两个氮化高峰连续的反应和短时间的高温后处理得到的复合材料性能最好；通过抗热震性能实验后复合材料的残余强度较高，显示出较好的抗热震性能。
