1.1.2 滑动(slip)滑动(slip ):在同步传输或准同步传输的比特流中由于缓冲存储器的读写速 率不一致造成一组比特丢失或重复插入的现象,称为滑动。滑动分为受控滑 动和非受控滑动。F面我们以E1芯片为例,看看滑动产生的原因。图1-1滑动产生的原理5E1接收芯片从输入信号中提取时钟,做为缓冲存储器的写时钟,而系统...
The Mg-4.58Gd-0.45Y-0.01Er alloys with different volume fractions of columnar crystals in hard orientation (orientation factor of basal plane slip system is less than 0.2) were prepared by changing the pulling rate to regulat...
were comparatively studied to investigate the effect of Y addition on microstructure evolution and mechanical properties.A huge increase of uniform elongation,from 5.3%to 20.7%,was achieved via only 3 wt%addition of yttrium.TEM results revealed that the only activated slip system in pure Mg was ...
However, on the contrary, using density-functional theory (DFT), the magnitude of generalized planar fault energy (GPFE) for the prismatic slip system was calculated to be decreased by Gd alloying [26]. It is generally accepted that the softening [26], rather than the strengthening of ...

Consequently, the c/a lattice parameter will increase, leading to an inhibition of slip planes in the HCP structure and changing the material strength and hardness [70]. L-PBF machines work under inert gas atmosphere, usually argon or nitrogen. It should be noted under nitrogen gas atmosphere ...

Using first-principles density functional theory, we find that bcc-Mg has a similar weight density of hcp-Mg, lower Young's modulus, and higher shear modulus than hcp-Mg, and the same conventional slip systems as the bcc structure. A simple theoretical model is developed to predict the ...
