Journal ArticleDOI
Temperature dependent deformation of the B2 austenite phase of a NiTi shape memory alloy
Othmane Benafan,Othmane Benafan,R.D. Noebe,Santo Padula,Anita Garg,Anita Garg,Bjørn Clausen,Sven C. Vogel,Raj Vaidyanathan +8 more
TL;DR: In this article, the B2 austenite phase of a polycrystalline Ni49.9Ti50.1 (at.%) shape memory alloy was studied through combined macroscopic and microstructural characterization efforts.
Journal ArticleDOI
Mechanical and functional behavior of a Ni-rich Ni50.3Ti29.7Hf20 high temperature shape memory alloy
Othmane Benafan,Anita Garg,Anita Garg,R.D. Noebe,G.S. Bigelow,Santo Padula,D. J. Gaydosh,Norbert Schell,J.H. Mabe,Raj Vaidyanathan +9 more
TL;DR: In this article, the mechanical and functional properties of Ni-rich Ni50.3Ti29.7Hf20 high temperature shape memory alloy were investigated through combined ex situ macroscopic experiments and in situ synchrotron X-ray diffraction.
Journal ArticleDOI
Role of B19′ martensite deformation in stabilizing two-way shape memory behavior in NiTi
Othmane Benafan,Othmane Benafan,Santo Padula,Ronald D. Noebe,Thomas A. Sisneros,Raj Vaidyanathan +5 more
TL;DR: In this article, the deformation of a B19′ martensitic, polycrystalline Ni49.9Ti50.1 (at. %) shape memory alloy and its influence on the magnitude and stability of the ensuing two-way shape memory effect was investigated by combined ex situ mechanical experimentation and in situ neutron diffraction measurements at stress and temperature.
Journal ArticleDOI
Additive manufacturing of NiTiHf high temperature shape memory alloy
Mohammad Elahinia,Narges Shayesteh Moghaddam,Amirhesam Amerinatanzi,Soheil Saedi,Guher P. Toker,Haluk E. Karaca,Glen Bigelow,Othmane Benafan +7 more
TL;DR: In this paper, a selective laser melting (SLM) process was used to develop components from NiTiHf powder (of approximately 25-75 m particle fractions), and the thermomechanical response was compared to the conventionally vacuum induction skull melted counterpart.
Journal ArticleDOI
Shape memory alloy actuator design: CASMART collaborative best practices and case studies
Othmane Benafan,J. Brown,Frederick T. Calkins,Parikshith K. Kumar,Aaron P. Stebner,Aaron P. Stebner,Travis L. Turner,Raj Vaidyanathan,John Richard Webster,Marcus L. Young,Marcus L. Young +10 more
TL;DR: Six fundamental design aspects of shape memory alloy components and systems, which include evaluation, alloy selection, processing and fabrication, testing and properties, modeling, and system integration considerations including control system design are identified.
