Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study

Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study, International Journal of Plasticity 60 (2014) 71–86. Martensitic tetragonal-to-monoclinic transformation in zirconia is a ‘‘double-edged sword’’, enabling transformation toughening or shape memory effects in favorable cases, but also cracks and phase degradation in undesirable scenarios.

PhD Studentship: In-situ quantification of interphase stress during martensitic transformations, Open University, UK

Fully funded PhD studentship at The Open Univeristy campus, Milton Keynes, UK. The aim of this project is to optimise experimental techniques such as digital image correlation (DIC) and focused ion beam (FIB) hole drilling to investigate the micro scale stresses and strains occurring during martensitic transformations. The techniques will be applied to a range of materials from simple steels to complex shape memory alloys. There will also be scope within the project to study martensitic alloys using central facilities such as the ILL, ESRF and Diamond light source.

Stress-induced phase transformation and pseudo-elastic/pseudo-plastic recovery in intermetallic Ni–Al nanowires

Dear friends,

I want to share our recent research work on NiAl nanowire, which is published in Nanotechnology, IOP publishing. The abstract of the paper is given below. Further details can be found at "Vijay Kumar Sutrakar et al 2009 Nanotechnology 20 295705 (9pp)   doi: 10.1088/0957-4484/20/29/295705"
