Elasticalorimetric Shape Memory Alloy Systems and The Effect of Pressure on Characteristic Properties of SMAs

Abstract

Shape memory alloys are the materials that can gain its original shape after the deformation caused by heat, pressure or magnetic field. In this work, we investigated the pressure effect on the characteristic phase transformation temperatures, order-disorder phase transitions and also the effect on morphology. Kinetic parameters were detected by thermal analysis results and activation energy variation was calculated. The morphological analyses were made at room temperature by XRD and optical microscope analysisthen the alterations in diffraction patterns were detected.
