Detwinning Behavior of Bismuth Single Crystals

Bismuth Flux Growth of CeRh6Ge4 and CeRh2Ge2 Single Crystals

Single crystals of the germanides CeRh6Ge4 and CeRh2Ge2 were synthesized from the elements in bismuth fluxes. Polycrystalline samples are available by arc-melting. The structures were refined on the basis of single-crystal X-ray diffractometer data. CeRh6Ge4: LiCo6P4 type, P6m2, a = 715.4(2), c = 385.5(1) pm, wR2 = 0.0554, 273 F2 values, 19 variables; CeRh2Ge2: ThCr2Si2 type, I4/mmm, a = 415.69...

Article history: Received 11 December 2015 Received in revised form 9 January 2016 Accepted 9 January 2016 Available online 25 January 2016 In thisworkwe present the high temperature functional behavior of the newNi50.3Ti25Hf24.7 shapememory alloy (SMA). Very high transformation strainsweremeasured during isobaric experiments at temperatures up to Af= 420 °C. For the [111]B2 orientation in tens...

Strain hardening behavior of aluminum alloyed Hadfield steel single crystals

Very high strain hardening coefficients (=G/23) are observed for aluminum-alloyed face-centered cubic Hadfield steel single crystals under tensile loading. Alloying with aluminum suppressed deformation twinning in two of the three crystallographic orientations studied, and transmission electron microscopy results revealed the existence of dense dislocation walls (sheets) along crystallographic ...

Wear of fluorapatite single crystals. II. Frictional behavior.

It is a convenient approximation to regard the frictional forces between two solids as made up of two components: the force required to shear adhering junctions in the region of surface contact and the force required to deform the underlying bulk material.' With an elastic solid, the deformation component may be due mainly to an elastic hysteresis loss; but if plastic flow occurs, the deformati...
