Additive manufacturing of shape memory alloys: A review with emphasis on powder bed systems
Autor: Ali N. Alagha, Shahadat Hussain, Wael Zaki
Publikováno v: Materials & Design, Vol 204, Iss , Pp 109654- (2021)
The ability of shape memory alloys (SMAs) to recover inelastic strains larger than any other metallic alloy has prompted their use in a wide range of applications. However, for the most common SMAs, including NiTi and Cu-based systems, fabrication us

Effective phase transformation behavior of NiTi triply periodic minimal surface architectures
Autor: Ali N. Alagha, Viet Nguyen, Wael Zaki
Publikováno v: Journal of Intelligent Material Systems and Structures. 34:672-695
The effective behavior of shape memory alloy triply periodic minimal surface (TPMS) structures is investigated using finite element analysis and numerical homogenization. The TPMS unit cells considered are primitive, IW-P, gyroid, and diamond subject

Effective Initial and Subsequent Loading Surfaces for Phase Transformation in TPMS-SMAs
Autor: Ali N. Alagha, Wael Zaki, N.V. Viet
Publikováno v: ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems.
In this paper, the effective behavior of shape memory alloy (SMA) triply periodic minimal surface (TPMS) structures is investigated by means of finite element analysis and numerical homogenization. For this purpose, the onset and subsequent threshold
