NiTi shape memory alloys (SMA) are broadly employed in multifunctional systems in several
industrial domains, like aerospace, automotive, biomedical and power plants. Their …

In near equiatomic NiTi alloys, the thermoelastic transformation between austenite and the R-
phase shows unique properties, which make the R-phase transformation very promising for …

This work studies the impact of selective laser melting (SLM) fabrication on the
microstructure and texture of Ni-rich NiTi alloy. SLM NiTi samples were fabricated with a …

Abstract Ni 51 Ti 49 at.% bulk was additively manufactured by laser-directed energy
deposition (DED) to reveal the microstructure evolution, phase distribution, and mechanical …

In order to take advantage of both grain refinement and precipitation hardening effects,
nanoscaled Ni 4 Ti 3 precipitates are introduced in a Ti–50.8 at.% Ni alloy with micron-sized …

Functional stability of superelasticity is crucial for practical applications of shape memory
alloys. It is degraded by a Lüders-like deformation with elevated local stress concentration …

This study investigated the effect of ageing on the transformation behaviour of a Ti–50.9 at.%
Ni alloy. Ageing at below 573K was found to suppress the original A↔ M transformation …

In this work, we proposed a process to improve the functional stability of Ni-rich NiTi alloys,
which combines surface nano-crystallization by means of ultrasonic shot peening and …

In this work, a new process is developed to improve the functional stability of Ni-rich NiTi
alloys. Repetitive temperature-and stress-induced phase transformation is first conducted to …

Shape Memory Alloys (SMAs), famous class of smart materials with unique functional and
intelligence properties, have attracted much attention in recent decades. These materials …
