The stabilization of transformation pathway in stress induced martensite

Scripta Metallurgica et Materialia, 1995
It has been recently shown that two way shape memory effect/TWSME/ in shape memory alloys/SMS/ can withstand opposite external forces (the transformation strain induced by thermal change and external stress have opposite signs) up to some level and therefore do work.

On the stress induced martensitic transformation compression test

Materials Science and Engineering: A, 1996
Abstract An analysis of the influence of the friction, which arises between the compression sample and the test machine, on the martensitic transformation of Cu Zn Al alloys was performed. It is shown that the error introduced by neglecting the friction term is greater than the typical error of tensile experiments.

Some Remarks on Thermodynamics of Stress‐Induced Martensitic Transformations

physica status solidi (b), 1985
AbstractThe thermodynamics of stress‐induced martensitic transformations is re‐examined based on the recently developed formulation of thermodynamics of stress‐induced first‐order solid‐solid phase transformations. The tacit assumptions to derive the Clausius‐Clapeyron equation for the Ms temperature are revealed and the effects of different elastic ...

Residual stresses induced by martensite transformation in NiTi alloy

SPIE Proceedings, 1999
In the paper an opportunity to initiate martensite transformation under ultrasound action is shown. The mathematical model for calculation of this effect has been applied.

Stress Induced Martensitic Transformation Studied by Neutron Diffraction

Materials Science Forum, 2002
Neutron diffraction is an ideal tool for the study of stress induced martensitic transformation. The method is well established for the measurement of internal stress in two phase materials, since its selectivity allows the partitioning of stress between phases and grain families to be determined.

The concern of elasticity in stress-induced martensitic transformation in NiTi

Materials Science and Engineering: A, 1999
Abstract It has been reported in the literature that moduli of elasticity of the austenite and martensite of near-equiatomic NiTi differ often by a factor of 3. It is expected that a phase transformation between the two phases may be induced by the application of a stress, according to thermodynamic principles.

In situ study of stress-induced martensitic transformation in TiNi

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2000
Abstract By means of synchrotron X-ray diffraction method the stress-induced martensite transformation in TiNi (with two different phase compositions) at room temperature was investigated in situ. It has been shown that in alloys with temperature-induced martensite in the initial state a non-periodic fluctuation of intensity of the X-ray reflexes ...

Stress Induced Martensitic Transformation in Ti-1023 Alloys

Materials Science Forum, 2016
Mechanical behaviors of isothermal hot forged and solution treated Ti-1023 alloy with different initial microstructures were investigated. After heat treatment at 760°C and 820°C for 1 hour, Ti-1023 alloys mainly consisted of fine α particles and β phase with a large grain size.

Stress-induced martensitic transformation in Fe–Ni bicrystals

Acta Materialia, 2001
Abstract The effect of applied stress on martensitic transformation behaviour near the grain boundary was examined using Fe–32 at.% Ni bicrystals containing a 90°〈2 1 1〉 tilt or a 90°{2 1 1} twist grain boundary focusing on the martensite-start stress (σM), the morphology of martensites and the variant selection.
