It involves production of NiTiW shape memory alloy Accepted 23 September 2012 thin films by Co-sputtering of NiTi and W targets. The grain size of B2-NiTi decreases with increasing W Available online 29 September 2012 content, due to the immiscible W layer obstructing its grain growth. Suresh S. Mechanical behavior of nanocrys- barriers to
Nov 30, 2010 · The TiNiW twophase shape memory alloy (SMA) thin film system is presented as a prototype for new SMAs with tailorable thermal transformation hysteresis (T).The concept is to combine the SMA TiNi with almost insoluble W to create the twophase system (TiNi)(W).This system behaves like a pseudobinary TiNi system. Dynamic thermo-mechanical behaviors of SME TiNi alloys Dynamic thermo-mechanical coupling behaviors of shape memory TiNi alloy in the strain rate ranging from 300 s1 to 2000 s1 are investigated by the split Hopkinson pressure bar (SHPB) device with an infrared (IR) detection system. In stressstrain space, dynamic response shows a strong strain hardening property, however, in stresstemperature space, transformation path is
Shape memory thin films deposited by sputtering are attractive candidates for micro-electro-mechanical-system (MEMS) because of their large deformation and strong recovery force. In the present study Ni-Ti thin films have been deposited on NaCl substrates by DC magnetron sputtering source fitted with an 80mm diameter alloy target. In order to obtain a variety of film Full article:Achieving large super-elasticity through Jan 23, 2021 · Inamura T, Fukui Y, Hosoda H, et al.

Dec 17, 2015 · The influence of structure refinement and electropulse current on strength, ductility, and deformability during cold rolling of over stoichiometric shape memory TiNi alloy is investigated. It was shown that strength increases but ductility decreases with grain refinement to nanosize scale. However, deformability and ductility may be enhanced significantly for Sudha Jayaprakasam - Google ScholarMicrostructure Evolution and Mechanical Behavior in Coarse Grained and Nanostructured Shape Memory TiNi Alloy:A Comparative Study AA Misochenko, JV Tilak, J Sudha, KA Padmanabhan, V Stolyarov 13th International Conference on Superplasticity in Advanced Materials ICSAM , 2018
