Dislocation mechanisms of creep in Ni3Al
The compressive creep deforrn;~tiort microstructure of polycrystalline Ni3AI h:is been observed by transnlission electron microscopy (TEM). ( 1 1 I ) rind ( 110) slip systems have been identified in primary creep. Dissociatiort of edge superparti:~l pairs perpendicular to the slip plane (both { 11 1 ) and ( 110) ) is common in crept specimens. I'he formation of this superdislocation...
متن کاملElectronic structure of Ni3Al and Ni3Ga alloys.
This work investigates the charge transfer and A1 (Ga) p-Ni d hybridization effects in the intermetallic Ni3Al (Ni3Ga) alloy using the Ni L3~and K-edge and Al (Ga) K x-ray absorption near edge structure (XANES) measurements. We find that the intensity of white-line features at the Ni L3~-edge in the Ni3Al (Ni3Ga) alloy decreased in comparison with that of pure Ni, which can be attributed to the...
متن کاملFlash Joule heating for ductilization of metallic glasses
Metallic glasses (MGs) inherit their amorphous structure from the liquid state, which predetermines their ability to withstand high loads approaching the theoretical limit. However, the absence of slip systems makes them very sensitive to the type of loading and extremely brittle in tension. The latter can be improved by precipitation of ductile crystals, which suppress a catastrophic propagati...
متن کاملParamagnetic properties of NdFeAsO0.94F0.06 polycrystals
The temperature and field dependencies of magnetization of NdFeAsO0.94F0.06 bulk sample are shown to exhibit the Curie-Weiss behaviour, both in the superconducting and normal states. To address the origin of the strong paramagnetic signal, particularly to reveal contributions from antiferromagnetic second phases in sintered NdFeAsO0.94F0.06, the magnetic response of Nd2O3 was measured and compa...
متن کاملTopological characteristics of plane sections of polycrystals
Homology metrics have been used to assess the connectivity of grain boundary networks in plane sections of polycrystals. The analysis is based on orientation maps, and four characteristic microstructure types were examined: SrTiO3 microstructures with normal and bimodal grain size distributions and two Ni microstructures with different concentrations of R3 grain boundaries. The inverse connecti...
