Effect of Co2 Laser on Some Properties of NI46TI50CU4 Shape Memory Alloy
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 2
Abstract
The microstructure, mechanical and corrosion properties of Nickel-Titanium-Copper shape memory alloy were studied in this paper. The Ni46-Ti50-Cu4alloy was prepared using the powder metallurgy technique, and then mixed and cold pressed at (600,700 and 800) MPa to arrangement cylindrical specimens of (11mm diameter×16.5mm length).After pressed the samples had sufficient green strength for handling. The specimens were consequently sintered at (850,900 and 950) ˚C for five hours in an electric vacuum furnace. The optimum compacting pressure and sintering temperature were identified using Minitab program. Samples prepared under the optimum process conditions were then irradiated using a continuous CO2 laser at5w, 10w and15w. Multiple investigations were conducted on the alloys including shape memory effect, microstructure, scanning electron microscopy (SEM) and hardness. The results indicate that increase hardness after Laser processing
