متن کاملLaser annealing of amorphous NiTi shape memory alloy thin films to locally induce shape memory properties
We present the results of a crystallization study on NiTi shape memory thin films in which amorphous films are annealed by a scanning laser. This technique has the advantage that shape memory properties can be spatially distributed as required by the application. A kinetics study shows that nucleation of the crystalline phase occurs homogenously in the films. Consequently, the laser annealing p...
متن کاملOn the Damping Behaviour of Niti Shape Memory Alloy
Shape memory alloys exhibit a high damping capacity in the mktensite state. Results obtained from both DMA and cyclic tests under tension-compression load show that the martensite damping capacity in NiTi SMAs is a function of both strain amplitude and annealing temperature. Internal friction due to movements of martensite twin boundaries within both elastic (accommodation) and inelastic (reori...
متن کاملEffects of VIM frequency on chemical composition, homogeneity and microstructure of NiTi shape memory alloy
The concentration distribution and microstructure of NiTi shape memory alloys produced in vacuum induction furnaces operating at high and medium frequencies are compared with those of materials melted in vacuum resistance furnaces. The production procedure consisted of charging pure metals into a graphite crucible; raising the temperature to 1450°C under vacuum; holding the materials in high an...
متن کاملUltrasonically assisted turning of NiTi based shape memory alloy
In this study, vibration cutting has been applied to machining of a novel material, NiTi based shape memory alloy (SMA), using a commercial ultrasonic piezoelectric transducer to vibrate an ISO insert CCMT geometry cutting tool. The effect of vibration in turning process was characterized by investigating the surface roughness of workpiece and surface quality assessment of machined surface usin...
