The new materials science diffractometer STRESS-SPEC at FRM-II
Michael Hofmann,Rainer Schneider,G.A. Seidl,Joana Rebelo-Kornmeier,Robert C. Wimpory,Ulf Garbe,Heinz Günter Brokmeier +6 more
TL;DR: In this paper, the Materials Science Diffractometer STRESS-SPEC at FRM-II is designed to be equally applied to texture or residual stress analysis by virtue of its flexible configuration and the high neutron flux at the sample position.

Statistical analysis of residual stress determinations using neutron diffraction
TL;DR: In this article, the authors present an overview of the main features that influence the residual stress and associated uncertainty determination, such as reference values, choice of moduli values, grain size effects and positioning etc.

Effects of surface roughness and training on the twinning stress of Ni―Mn―Ga single crystals
Markus Chmielus,Katharina Rolfs,Robert C. Wimpory,Walter Reimers,Peter Müllner,Rainer Schneider +5 more
TL;DR: In this article, it was shown that different surface treatments in combination with repeated mechanical deformation experiments significantly reduce the twinning stress, regardless of whether or not electropolishing is used.

Efficiency Boost of the Materials Science Diffractometer E3 at BENSC: One Order of Magnitude Due to a Horizontally and Vertically Focusing Monochromator
TL;DR: In this paper, a new vertically focusing and horizontally bent perfect Si single crystal monochromator was used for residual stress experiments at the HMI, Berlin, to improve the performance of residual strain and texture diffractometer.

Effects of surface damage on twinning stress and the stability of twin microstructures of magnetic shape memory alloys
TL;DR: In this paper, the effect of surface damage on the mechanical properties and twin structure of Ni-Mn-Ga single crystals was studied and the amount of damage was characterized with X-ray diffraction: damage causes peak broadening.
