change in microstructure
例句与用法
- Cyclic pressing is a new kind of densification processing , which is introduced to densify as - deposited ring of al - 20 % si / sicp . this paper includes the densification result and rule of this technics . the research shows that this technics can be successfully used to densify spray - forming porous material and can be availably adopted to improve mechanical performance and microstructure . this technics is characterized by simple equipment 、 small expense and flexible process , and these characters will make it come true to producing spray - deposited rings less costly
本文采用一种新型致密化工艺?楔压工艺?对喷射沉积al - 20 % si / sicp大环进行了致密化加工,采用密度硬度分布、抗拉强度变化和检测显微组织变化的实验研究方法对其致密化效果及该工艺规律进行了研究,通过研究表明了楔压工艺可以成功地用来致密化喷射沉积多孔材料,该工艺有效地提高了喷射沉积大环件的致密度和抗拉强度并改善了组织。 - Microstructural change and thermal shock performance of metal / ceramic graded thermal barrier coatings in thermal shock experiments were studied by scanning electron microscope and energy - dispersive spectrometry . the results showed : 1 ) metal microstructure kept intact while ceramic microstructure had been destroyed ; 2 ) thermal shock performance of coatings was interrelated with its function to relax residual stresses , therefore thermal shock performance of gradient thermal barrier coatings was better than that of terraced thermal barrier coatings ; 3 ) thermal shock performance was concerned with metal content in metal / ceramic thermal barrier coatings , which would be improved when metal content was increased
利用扫描电子显微镜和能谱成分分析技术研究了金属/陶瓷梯度热障涂层在热震过程中的显微组织变化及其抗热震性能.结果表明： 1 )金属显微组织保持完好，陶瓷显微组织有明显的破坏； 2 )涂层抗热震性能与其热应力缓和功能密切相关，梯度热障涂层比阶梯热障涂层具有更高的抗热震性能； 3 )金属/陶瓷热障涂层抗热震性能与其中金属相含量有关，金属相含量增加可改善涂层抗热震性能
