Electron Microscopy Study of Stress - induced Acicular γ ' Martensite in Cu - Al - Ni Alloy

چکیده
spear-like martensite thermally formed in the same alloy in several respects such as in shape, lattice invariant shear, habit plane and orientation relationship, even though both have the same crystal structure and lattice parameters. The lattice invariant strain of the martensite was found to be stacking faults on the basal plane, and a defectless region was observed at the middle of the martensite, which is in sharp contrast to the midribs in ferrous twinned martensites. The habit plane

Experimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals
Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
متن کاملOptical Microscope Study of the y ( FCC ) we ( HC ) Martensitic Transformation of a Fe - 16 % Mn - 9 % Cr - 5 % Si - 4 % Ni Shape Memory Alloy
The y(FCC)tt&(HC) transformation is studied by light optical microscopy and scanning electron microscopy in a polycrystalline Fe-Mn-Si-Cr-Ni shape memory alloy. Thermal and stress-induced martensites are both studied to point out differences. A color etching method permitted to clearly observe morphological evolutions during the transformation and its reversion. Deformations of a golden microgr...
متن کاملThe Thermomechanical Behaviour of a Metastable Cu-Al-Ni Single Crystal Alloy
This paper presents the results from an experimental and theoretical analysis of the thermomechanical behaviour of a metastable P-phase single crystal alloy of composition Cu 28.3at% A1 3.8at% Ni. The stress-strain behaviour of this single crystal material was investigated experimentally by tensile testing and this data was used to characterise the stress1 temperature martensite phase equilibri...
متن کاملMartensitic transformation and magnetic properties of Heusler alloy Ni–Fe–Ga ribbon
The martensitic transformation and magnetic properties of ferromagnetic shape memory alloy Ni50+ xFe25− xGa25 (x = −1, 0, 1, 2, 3, 4) ribbons have been systematically studied. It has been found that with the increase of Ni concentration, the martensitic transformation temperature increases, but the Curie temperature decreases. Both the two-step thermally induced structural transformation and th...
متن کاملElectron Microscopy Studies of Martensite Microstructures
An overview will be given of some recent results of microstructural electron microscopy studies on martensitic systems. The precursor structure observed in a ternary Ni-Mn-Ti alloy and its correlation with the ensuing stacking sequence is presented. New types of materials of a well known alloy, in casu splat-cooled and nanoscale thin films of Ni-A1 are investigated revealing particular morpholo...
