形成相的英文
sigma formation
例句与用法
- The results showed that it is impossible for " island - sea " structure non - compatible blend polymer to form interfacial phase separated micro - void after being drawn
结果表明对于“海?岛结构”非相容性共混高聚物中空纤维，经拉伸后，能形成相界面分离孔。 - This was due to three reasons : ( 1 ) baso4 particles were rigid inorganic particles , which could hinder the retraction of polymer molecules and decreased the elasticity . ( 2 ) a bad compatibility between baso4 and tpu , small interface adhesive force and the phase interface ready to separate . ( 3 ) during high content of baso4 , the tenacity of filament mainly depended on tpu , so that the strength decreased with the content of tpu in filament down
这是因为： baso _ 4属于刚性粒子，阻碍tpu大分子链的回缩，降低了纤维的弹性； baso _ 4与tpu相容性极差，共混时容易形成相界面，界面结合力小，受外力作用时相与相间容易发生分离，使纤维的力学性能下降； baso _ 4在高含量下，纤维强度主要由聚合物的力学性能决定，随着baso4含量的增加， tpu所占比例下降，从而在宏观上表现出纤维的力学性能下降。 - It is shown that the high hardness and low thermal conductivity promote the formation of transformed asbs , and the deformed asbs will form if low hardness and high thermal conductivity are involved ; for steel with both high hardness and thermal conductivity , the transformed asbs will transform into deformed ones , due to that the fast heat conduction from high temperature asbs results in rapid temperature rise around and thus decreasing the hardness
研究结果表明：钢的高硬度和低热导率有利于形成相变带；反之，则倾向于形成变带；对于具有高硬度和高热导率的钢，由于高温相变带区域的热量迅速传递到周围的基体组织而使其温度升高、硬度降底，形成的相变带会向形变带转化。 - The effects of the fabrication and heat - treatment methods on the microstructures and properties of the nb - si system intermetallics have been studied and the optimized nb - si intermetallic system as well as the optimized fabrication and processing procedures have been selected . the presence of alloying elements as well as the morphology and microstructure of the compound phases with these elements has been investigated . the effects of the alloying elements on the high - temperature oxidation behavior of the nb - si system intermetallics have also been studied
本文研究了不同的制备工艺和热处理制度对nb - si系金属间化合物显微组织和性能的影响，优选了合适的材料体系、制备工艺和热处理制度，分析了微合金化元素及其形成相的组织、结构、形态、存在形式等及其对材料高温抗氧化行为的影响，提出了材料高温抗氧化行为和室温断裂行为的微观机制，为研制nb - si系金属间化合物基高温结构材料奠定了一定的基础。
