蠕變發裂蠕變 的英文怎麼說
中文拼音 [rúbiànfālièrúbiàn]-
The knowledge on the properties of used materials is urgently needed for reasonable life - prediction and life - distribution. as cylinder bolts are concerned, they often rapture at the first tooth - root resulting from lower high temperature strength of their material and higher stress. since bolts operate at high temperature environment, creep skew and damage causing their failure are important factors that can not been neglected
就汽缸螺栓而言，由於螺栓材料的高溫強度偏低，預緊力過大，常常在螺栓的第一齒根部位發生蠕變脆性斷裂，因其長期在高溫環境下工作，蠕變變形和蠕變損傷是其失效的一個不可忽略的重要因素。The presence of small amount of liquid at grain boundaries tends to form thin viscous layer which surrounds the finer grains. intergranular fracture may occur at the grain boundaries between two fine grains not covered by viscous phases. the high ductility achieved at low strain rates is generally attributed to dislocation glide - creep accommodation mechanisms
原始晶界上產生少量液相，形成薄的固液共存粘性層並包圍細化的晶粒，沿晶斷裂主要發生在無粘性層的細晶粒間；而在較低應變速率下，三叉晶界位錯攀援?蠕變協調機制鬆弛晶界滑移產生的應力集中，晶界上產生較多液相，有利於晶界滑移進行。It seemed that the fiber and the matrix did not creep themselves in the range of the testing stress and temperature, so the matrix microcracking and interfacial sliding will be the main contributer to the macroscopic deformation of the three - dimensional c / sic composite
由於在所測定的溫度區間和應力范圍內，碳纖維和基體本身都不大可能發生蠕變。因此，基體開裂和界面的滑動是3d - c sic復合材料宏觀變形的主要貢獻者。
