Stress-induced FCC/FCT phase transformation in Fe–Pd alloy
We report stress-induced martensitic transformation in tensile loaded Fe–30.5 at.% Pd polycrystals, mainly using optical microscopy. Reverse transformation occurs during unloading. Thermodynamic relationships between applied stress, transformation strain and the latent heat of transformation are examined. 2002 Acta Materialia Inc. Published by Elsevier Science Ltd.

متن کاملPhase Transformation and Hydrogen Storage Properties of an La7.0Mg75.5Ni17.5 Hydrogen Storage Alloy
X-ray diffraction showed that an La7.0Mg75.5Ni17.5 alloy prepared via inductive melting was composed of an La2Mg17 phase, an LaMg2Ni phase, and an Mg2Ni phase. After the first hydrogen absorption/desorption process, the phases of the alloy turned into an La–H phase, an Mg phase, and an Mg2Ni phase. The enthalpy and entropy derived from the van’t Hoff equation for hydriding were −42.30 kJ·mol−1 ...
متن کاملPhase Transformation Induced Self-Healing Behavior of Al-Ag Alloy
Self-healing alloys are promising materials that can decrease the consequences of accidents. To detect crack formation in a material is simple task that can be performed by e.g., sonic or ultrasound detection, but it is not always possible to immediately replace the damaged parts. In this situation, it is very advantageous to have the chance to heal the crack during operation, which can be done...
متن کاملSolid-Solid Phase Transformation Kinetics
Natural formation of the bcc modification for Co was demonstrated to occur upon precipitation of Co in supersaturated Au90Co10 alloy. The microstructural evolution was investigated by high resolution transmission electron microscopy. Co precipitation starts with the formation of very thin coherent plates along {100}Au. This initially precipitated Co was shown to be a hitherto unknown metastable...
