位错蠕变 meaning in Chinese

dislocation creep

From an examination of the tensile behavior of cz ly12 alloys under different temperature and strain rate , two kinds of deformation and intergranular fracture behaviors were observed that were opposite to the characteristic strain rate range in fine - grained superplasticity . the mechanisms are described as follows . the high ductility achieved at high strain rate is generally attributed to the dominant role of gbs accommodating mechanisms , which is considered as dislocation creep within grains controlled by subgrains
研究选用自然时效淬火态的ly12铝合金，进行了一系列不同温度和应变速率下的单轴拉伸试验， 480下，观察到与传统细晶超塑性特征区间相反的行为：较高应变速率下，动态再结晶使晶粒细化，促进了晶界滑移，亚晶界控制的晶内位错蠕变是晶界滑移的主要协调机制。
