Face-centered cubic (fcc) to body-centered cubic (bcc) martensitic transformations occur in many materials, such as steels, FeNi meteorites or brass. The phenomenological theory has been the accepted theory for these transformations for more than half a ce ...
Directional transformation of a hypo-peritectic Fe–17.5 at.% Co alloy was studied. Two consecutive phase transformations—solidification (liquid to delta ferrite) and solid-state transformation (δ ferrite to γ austenite)—were observed and compared with theo ...
Bhadeshia recently claimed that the two-step theory of martensitic transformation was mathematically incorrect and incapable of making predictions about the observed pole figures. The present paper argues that his comments are not justified and that his al ...
The combined influence of prior plastic strain in austenite and applied stress in the course of the transformation on the crystallographic texture of bainitic steel was studied. The experimental data were obtained using electron back scatter diffraction an ...
The goal of this project was to develop low-firing thick-film materials systems for the fabrication of piezoresistive sensors on special steels, for the fabrication of instrumented medical devices. To this end, a series of individual thick-film materials a ...
We investigate the effect of martensitic phase transformations on the dynamic response of commercial AFM silicon cantilevers coated with shape memory alloy (SMA) thin films. We propose a simple thermo-mechanical model to predict the phase transformation. W ...
Energy transfer from phosphorescent ruthenium complex N877 dissolved in the liquid electrolyte to the squaraine sensitizer SQ1 anchored on the titanium oxide surface resulted in a four fold increase in external quantum efficiency in the blue part of the vi ...
NiTi alloy wires were embedded during the infusion processing of woven carbon fibre reinforced plastic (CFRP) composite plates with the purpose to passively increase their damping. Two types of NiTi wires, having the same diameter of 203 mu m, were conside ...

The internal friction phenomenon in metallic and polymeric shape memory materials is analyzed. The experimental results permit validation of a theoretical model which describes qualitatively the temperature dependence of the internal friction for the inves ...
Seven alloys of the ternary Au-Cu-Pt system, containing 75 or 76.5 wt.% Au with 0-15 wt.% Pt and heat-treated to a fully ordered condition, are examined using in-situ synchrotron radiation to determine transformation temperatures and phases formed, and to ...
