grain boundary sliding

基本解釋

The main obtained results are as follows: (1) there are extensive grain-boundary sliding and grain rotation during superplastic deformation;
所獲得的主要結(jié)果如下：（1）超塑性變形過程中存在廣泛的晶界滑動和晶粒轉(zhuǎn)動。
It was thought that the dislocation motion in grains and grain-boundaries, as an important coordination mechanism, promoted the development of grain-boundary sliding.
研究認(rèn)為，品界和晶內(nèi)位借運(yùn)動作為重要的協(xié)調(diào)機(jī)制，促進(jìn)了晶界滑動的順利進(jìn)行。
The deformation mechanism of the compression superplasticity of commercial AZ31 magnesium alloy-extruded is grain boundary sliding mechanism in coordination with the dynamic recrystallization.
工業(yè)擠壓態(tài)AZ31鎂合金壓縮超塑性變形機(jī)制為動態(tài)再結(jié)晶協(xié)調(diào)下的晶界滑移機(jī)制。

晶界滑動
In a large size grain (about 40-50 um), the dislocation sliding and twinning are the main deformation mechanism, and in a small size grain (5-20 um), grain boundary sliding is another important mechanism to improve the ductility of magnesium alloy.
在40～50μm的大晶粒中，變形機(jī)制以滑移和孿生為主，而在5～20μm的小晶粒中，晶界滑動機(jī)制發(fā)揮了重要作用，它可以協(xié)調(diào)大尺寸晶粒的變形，對提高鎂合金變形能力起有益的補(bǔ)充作用。

晶界滑移
As known from the dislocation theory, dislocations seldom appear in the grain interior, and the plasticdeformation of nanocrystallite mainly carries out by the grain boundary sliding and grain rotation.
小晶粒尺寸納米晶體內(nèi)部很少存在位錯，納米晶體的塑性變形主要依靠晶界滑移和晶粒的轉(zhuǎn)動來實(shí)現(xiàn)。
