Journal ArticleDOI
Studies on the effect of grain refinement and thermal processing on shape memory characteristics of Cu–Al–Ni alloys
TL;DR: In this article, a grain refinement and thermomechanical processing of Ni-Ti shape memory alloys has been conducted to increase the shape memory characteristics and ductility of copper-based alloys.
Journal ArticleDOI

U.S. Mallik,V. Sampath +1 more
TL;DR: In this paper, the shape memory effect and superelasticity of shape memory alloys with 10−14.5% of aluminum and 0−10% of manganese were studied.
Journal ArticleDOI
Reversible magnetocaloric effect in materials with first order phase transitions in cyclic magnetic fields: Fe48Rh52 and Sm0.6Sr0.4MnO3
A. M. Aliev,A. B. Batdalov,L. N. Khanov,Alexander P. Kamantsev,Victor Koledov,Alexey Mashirov,Vladimir G. Shavrov,Rostislav Grechishkin,Andrey R. Kaul,V. Sampath +9 more
TL;DR: The magnetocaloric effect in an Fe48Rh52 alloy and Sm 0.6Sr0.4MnO3 manganite was studied in cyclic magnetic fields as discussed by the authors.
Journal ArticleDOI
Improvement of Shape-Memory Characteristics and Mechanical Properties of Copper–Zinc–Aluminum Shape-Memory Alloy with Low Aluminum Content by Grain Refinement
TL;DR: In this article, grain refining was used to overcome the formation of coarse grains during casting, grain-refining additions were made to the liquid alloy, but the extent of grain refining achieved and its effect on the shape recovery strain varies from one study to another.
Journal ArticleDOI
Composite Materials Based on Shape-Memory Ti2NiCu Alloy for Frontier Micro- and Nanomechanical Applications

TL;DR: In this paper, the shape memory effect (SME) of composite materials based on Ti2NiCu alloy has been demonstrated and three approaches to realize this objective are demonstrated: the first one involves creating an amorphous-crystalline composite by passing accurately controlled electrical pulses through a rapidly-quenched ammorphous Ti 2NiCu ribbon, which can be trained to undergo reversible deformations by a single bend in the martensitic condition.
