Nickel-titanium (NiTi) shape memory alloys are used in varied engineering products, such as biomedical device and mechatronic actuator applications. The conventional machining technology utilized the limited fields due to their effects on hardness brittleness of machined alloys. However, wire electrical discharge (WEDM) is one most preferred post-processing tool obtain a surface with high quali...

background: the most favorable feature of nickel-titanium (ni-ti) alloys in orthodontics is producing constant forces in a wide deformation range. ni-ti closed coils produce compressive strength and can be used for several purposes such as space closure. the aim of this study was to evaluate the effects of the aging process (temperature changes and prolonged strain) on ni-ti closed coils and to...

Abstract Titanium alloy Ti6Al4V is widely used in aerospace, shipbuilding, petrochemical, and other industrial fields. Low-speed wire-cut electrical discharge machining (LS-WEDM) has the advantage of high accuracy. However, there are few research studies on comprehensive effects parameters TC4 (Ti6Al4V) made by LS-WEDM surface. This paper focuses titanium investigates surface roughness, kerf wi...

A bare AISI420J2 punch often suffers from severe adhesion of metallic titanium as well oxide debris particles in dry, cold forging biomedical alloys. This was plasma-carburized at 673 K for 14.4 ks to harden it up 1200 HV on average and achieve carbon supersaturation the carburized layer. employed cold, dry a pure wire into flat plate while reducing thickness by 70%. The contact interface width...
