High temperature β phase decomposition process in a Cu–Al–Ni shape memory alloy

TL;DR: In this article, the atomic order and the precipitation processes of the metastable β phase during heating in a Cu-13.15% Al-3.25% Ni shape memory alloy processed by powder metallurgy, have been studied by differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and in situ neutron powder diffraction.

Electron crystallography of zeolites--the MWW family as a test of direct 3D structure determination.

TL;DR: The efficacy of direct methods for solving the crystal structures of zeolites from electron diffraction data is evaluated for a series of related materials and it is clear that better specimen preparation methods are required to include projections containing the c( *) axis of the reciprocal lattice.

Characterization of hydroxyapatite/nano-zirconia composite coatings deposited by high velocity oxy-fuel (HVOF) spray process

TL;DR: In this paper, nano-indentation on polished cross-sections was used to determine the elastic modulus of the nano-zirconia composite coatings, which revealed Young's modulus value of ∼130 GPa.

Hydrogen effects on the magnetic properties of RFe11Ti compounds

TL;DR: In this paper, the location of hydrogen atoms within the crystal structure is given according to neutron diffraction experiments performed on CeFe 11 TiH, GdFe 11TiH, gdFe11 TiH and SmFe 11 tiH, which is a potential candidate for high performance permanent magnets.
