Thermomechanical study of Ni‐Ti alloys

Journal of Biomedical Materials Research, 1988
AbstractA preliminary study was conducted to demonstrate the usefulness of the combined technique of differential scanning calorimetry (DSC) and mechanical testing for the shape memory metals of 54NiTi and 53NiTiCo(3%) alloys. The DSC technique was used to measure precise transformation temperatures and the amount of thermal energy required for the ...

Electro-sinter-forged Ni–Ti alloy

Intermetallics, 2016
An innovative powder metallurgical process (Electro-Sinter-Forging - ESF) has been applied to a gas atomized Ni-Ti powder to avoid the typical drawbacks of the conventional industrial processing of this material: oxygen pick up, high processing temperature and slow cooling rate. At the same time, the ESF allows to overcome the low sintering activity of

Grindability of cast Ti–Cu alloys

Dental Materials, 2003
The purpose of the present study was to evaluate the grindability of a series of cast Ti-Cu alloys in order to develop a titanium alloy with better grindability than commercially pure titanium (CP Ti), which is considered to be one of the most difficult metals to machine.Experimental Ti-Cu alloys (0.5, 1.0, 2.0, 5.0, and 10.0 mass% Cu) were made in an ...

Elastic moduli of cast Ti–Au, Ti–Ag, and Ti–Cu alloys

Dental Materials, 2006
This study investigated the effect of alloying titanium with gold, silver, or copper on the elastic properties of the alloys.A series of binary titanium alloys was made with four concentrations of gold, silver, or copper (5, 10, 20, and 30 mass%) in an argon-arc melting furnace.

Thermodynamic properties of Ti in Ag–Ti alloys

Materials Science and Engineering: A, 2000
Abstract The thermodynamic properties of Ti in Ag–Ti alloys at 1273 K were determined using an oxygen sensor employing ZrO 2 (2.14 wt% MgO) as the solid electrolyte. TiO was identified as the equilibrium phase in the interface reaction layer formed by the reaction of Ti with Al 2 O 3 at 1273 K. From the standard Gibbs energy of formation of TiO and

Ti-Based Biomedical Alloys

2019
Titanium (Ti) and its alloys are currently getting much attention for structural biomaterials, because they are much advantageous as compared with other metallic biomaterials such as biomedical stainless steels and Co-based alloys, and their practical uses in implant devices are widely spreading.

Mechanical alloying of the Al–Ti system

Philosophical Magazine B, 1990
Abstract We have investigated the possibility of an amorphization reaction by mechanical alloying for two compositions of the Al–Ti binary system. While the Al-rich composition Al75Ti25 appears to give, after milling for 21 h, an Al(Ti) highly cubic phase, the Ti-rich composition Al25Ti75 does amorphize using various milling conditions. The progress of
