12Cooling rate effects on the structure and transformation behavior of Cu-Zn-Al shape memory alloys显示文摘Different fragments of a hot-rolled and homogenized Cu–Zn–Al shape memory alloy(SMA) were subjected to thermal cycling by means of a differential scanning calorimetric(DSC) device. During thermal cycling, heating was performed at the same constant rate of increasing temperature while cooling was carried out at different rates of decreasing temperature. For each cooling rate, the temperature decreased in the same thermal interval. During each cooling stage, an exothermic peak(maximum) was observed on the DSC thermogram. This peak was associated with forward martensitic transformation. The DSC thermograms were analyzed with PROTEUS software: the critical martensitic transformation start(Ms) and finish(Mf) temperatures were determined by means of integral and tangent methods, and the dissipated heat was evaluated by the area between the corresponding maximum plot and a sigmoid baseline. The effects of the increase in cooling rate, assessed from a calorimetric viewpoint, consisted in the augmentation of the exothermic peak and the delay of direct martensitic transformation. The latter had the tendency to move to lower critical transformation temperatures. The martensite plates changed in morphology by becoming more oriented and by an augmenting in surface relief, which corresponded with the increase in cooling rate as observed by scanning electron microscopy(SEM) and atomic force microscopy(AFM).Nicoleta-Monica Lohan Marius-Gabriel Suru Bogdan Pricop Leandru-Gheorghe Bujoreanu 2014International Journal of Minerals,Metallurgy and Materials2014,21,11:0
13Investigations of a nanostructured FeMnSi shape memory alloy produced via severe plastic deformation显示文摘Low-cost iron-based shape memory alloys(SMAs) show great potential for engineering applications. The developments of new processing techniques have recently enabled the production of nanocrystalline materials with improved properties. These developments have opened avenues for newer applications for SMAs. The influence of severe plastic deformation induced by the high-speed high-pressure torsion(HSHPT) process on the microstructural evolution of an Fe–Mn–Si–Cr alloy was investigated. Transmission electron microscopic analysis of the alloy revealed the existence of nanoscale grains with an abundance of stacking faults. The high density of dislocations characteristic of severe plastic deformation was not observed in this alloy. X-ray diffraction studies revealed the presence of ε-martensite with an HCP crystal structure and γ-phase with an FCC structure.Gheorghe Gurau Carmela Gurau Vedamanickam Sampath Leandru Gheorghe Bujoreanu 2016International Journal of Minerals,Metallurgy and Materials2016,23,11:0
