One-step model of the face-centred-cubic to body-centred-cubic martensitic transformation
TL;DR: In this paper, a one-step theory based on Pitsch distortion is proposed to explain the continuity between the orientations of the Kurdjumov-Sachs (KS), Nishiyama-Wassermann (NW) and Pitsch variants observed on the electron backscatter diffraction pole figures of martensitic alloys.

Formation of a shock deformation induced ω phase in Zr 20 Nb alloy
Gautam Kumar Dey,Raghvendra Tewari,Srikumar Banerjee,G. Jyoti,Satish C. Gupta,Keshaw D Joshi,S. K. Sikka +6 more
TL;DR: In this article, the formation of a plate shaped ω phase in Zr-Nb alloy after shock deformation has been studied with a view to ascertaining the nature of this transformation.

Orientation dependence of stress-induced phase transformation and dislocation plasticity in NiTi shape memory alloys on the micro scale
TL;DR: In this article, a binary, solution annealed precipitate free NiTi alloy was used to compress small pillars in three directions: 1, 2, 3 and 4 directions.

Mechanism of an adsorbate-induced surface phase transformation: CO on Pt(100)
TL;DR: In this article, the authors investigated the mechanism of the (5×20) → (1times;1) transition of Pt(100) during adsorption of CO using a fast Video-LEED technique.

Helium trapping at dislocations, precipitates and grain boundaries
TL;DR: In this paper, the authors studied the role of interfacial dislocations in bubble formation at grain and interphase boundaries but not at Tic-matrix interfaces, and found that high trapping of helium was observed at tic precipitatematrix interface which is attributed to an inhomogeneous ripening mechanism.
