The title compounds were prepared by melting and annealing of stoichiometric mixtures of the elemental components in a high-frequency furnace. They are isotypic with Yb2Ru3Ga10 (P4/mbm, Z = 2). Their lattice constants were determined from X-ray powder data, and their crystal structures were refined from single-crystal X-ray data. Er2Os3Ga10: a = 883.4(1), c = 636.7(1) pm, R = 0.025 for 506 Fo v...

In the actuation field, the most common shape memory alloy is quasi-equiatomic NiTi system, commercially known as Nitinol®. Ti-rich NiTi compounds show characteristic transformation temperatures higher than the room one and they can recover high values of deformation. Moreover, these intermetallic compounds are widely used since they exhibit high thermal and mechanical cycling stability. Other ...

Methods of structure determination from powder diffraction of non-molecular compounds (inorganics, extended solids, intermetallic compounds, etc.) are reviewed. They work either in reciprocal space or in direct space. Those working in reciprocal space use algorithms known from single crystal works (direct methods and Patterson synthesis) and need decomposition of powder patterns to individual r...
