Laves phase Titanium alloy Deformation Mechanical strength Fracture analysis Shear band 1. 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...
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- x Co x )2 forms within a broad homogeneity range of 0.127(3) x 0.937(8) at 1100 掳C. The distribution of chromium and cobalt atoms on the crystallographic positions 2 a and 6 h has been studied by single crystal structure analysis and a statistical mechanics ...
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 ...

They often possess extended ...
Alloys having an x value of from 0.49 to 0.61 are dominated by a C14 Laves phase crystal structure. As Ti-content increases, lattice constants a and c decrease non linearly, the absolute value of hydride heat of formation decreases, the total gas-phase storage capacity decreases and the high...
