First of all, it should be noted that the formation of the Laves phase in the alloy is a gradual phase transformation process, the initial Laves phase is oversaturated with Ti and has a chemical composition close to that of Ti(Ti,Al)2, then with increasing isothermal holding time it ...
时Ti.(50一x)Mn—t0Cr-xV(x=O,8.j2,t6,20,24,28,32)合金的研究表明,随着 合金中v含量的增加,台金由C14 Laves相变为C14 Laves相与BCC相共存,再变 为单一的BCC相结构。V含量的增加导致合金的吸氢容量增加、吸放氢平台变得平 坦、平台压力降低以及放氢过程中合金中残余氢容量增加。BCC相合金吸氢过程会...

Consequences of Crystal Structure Differences between C14, C15, and C36 Laves Phase Polytypes for their Coexistence in Transition-Metal-Based SystemsIn various binary and ternary transition-metal-based systems, two or even three different polytypes of Laves phases coexist as equilibrium phases. A ...
Among these is a C14-like Laves phase, u -(Ti-Zr-Ni), which forms at a composition Ti 37 Zr 33 Ni 30 . The crystal structure of this phase is determined by a Rietveld analysis. Ab initio calculations are used to confirm the structural details and to investigate the energetic stability...
The C14 phase Nb(Cr1-xCox)(2) forms within a broad homogencity range of 0.127(3) <= x <= 0.937(8) at 1100 degrees C. The distribution of chromium and cobalt atoms on the crystallographic positions 2a and 6h has been studied by a single crystal structure analysis and a statistical ...

Introduction AB2 type Laves phases are well-known for their topologically closed-packed structure among other intermetallic phases [1]. Laves phases have gained much attention in the last 20 years due to their...
