Assuming that the transient regimes prior to the onset of steady-state swelling correspond to the void nucleation stage, the effect of crystallographic structure (bcc vs. fcc) or Cr alloying on the void nucleation rate under a given amount of supersaturated vacancies was examined. It was found ...
Plane-wave expansion method was used to calculate absolute bandgaps of photonic crystal with FCC opposite-phase close packing structure. 本文的目的是研究FCC反相密堆积结构光子晶体在改变其结构的情况下完全禁带的变化。 更多例句>> 5) metastable bcc structure 亚稳bcc结构6...
Tags Fcc Process Structure Nov 21, 2009 #1 aiklone1314 25 0 i study from some books that the properties of a materials depends on the structure of it, while the structure depends on how it being process..may i know what structure actually it means? i can't get its meani...
Hume–Rothery's further work has shown that electron-concentration principles similar to those established for the noble metals and their alloys apply also to the solid solutions of a number of transition metals, particularly those with the fcc structure (Hume–Rothery [1966]). Figure 7 shows the...
Calculate the radius of iridium at, given that Ir has an FCC crystal structure, a density of 22.4 g/cm^3, and an atomic weight of 192.2 g/mol. Calculate the Planar Density (atoms/nm^2) of Atoms in the (111) plane of BCC Molybdenum. The lattice parameter...

Although the displacement field is not large enough for crack propagation, partial slips are observed along {110} planes in the vicinity of the crack tip, and an fcc crystal part appears as well. {100} is not due to the plastic relaxation but due to this crack-propagation property of bcc...
Results Grain boundary character and local hydrostatic stress. Grain boundary character described in terms of GB energy and structure has long been studied in bcc, fcc and hcp metals9,47–51. The 36 [100] equilibrium symmetric tilt grain boundaries (STGBs) with misorientation angle θ ...
Nanometre fcc clusters versus bulk bcc alloy: the structure of Cu-Pd catalysts 来自 Semantic Scholar 喜欢 0 阅读量: 31 作者:YANG,V Shah,LIQIU 摘要: We present a simple method to improve the accuracy of the calculated heat of mixing for the Cu-Pd alloy within the formalism of the ...
the mechanical performance of engineering materials operating at cryogenic temperatures has become a demanding feature, leading to the development of several high/medium entropy alloys with a face-centered cubic (fcc) structure (Gludovatz et al., 2014; Sathiyamoorthi et al., 2019; Sun et al., ...
