Benchmarking of several material constitutive models for tribology, wear, and other mechanical deformation simulations of Ti6Al4V Open
Use of an alpha-beta (multiphase HCP-BCC) titanium alloy, Ti6Al4V, is ubiquitous in a wide range of engineering applications. The previous decade of finite element analysis research on various titanium alloys for numerous biomedical applic…

MACHINABILITY COMPARISON BETWEEN TWO DIFFERENT GRADES OF TITANIUM ALLOYS UNDER DIVERSE TURNING AND COOLING CONDITIONS: Ti-6Al-4V and Ti-5Al-5V-5Mo-3Cr Open
The machining of a new alloy often presents a challenge. While useful assumptions can be drawn from materials of similar properties, there will always be unpredictable outcomes. Titanium alloys have been employed in the aerospace industry …

Cutting Performance of Low Stress Thick TiAlN PVD Coatings during Machining of Compacted Graphite Cast Iron (CGI) Open
A new family of physical vapor deposited (PVD) coatings is presented in this paper. These coatings are deposited by a superfine cathode (SFC) using the arc method. They combine a smooth surface, high hardness, and low residual stresses. Th…

Tribological and Wear Performance of Carbide Tools with TiB2 PVD Coating under Varying Machining Conditions of TiAl6V4 Aerospace Alloy Open
Tribological phenomena and tool wear mechanisms during machining of hard-to-cut TiAl6V4 aerospace alloy have been investigated in detail. Since cutting tool wear is directly affected by tribological phenomena occurring between the surfaces…
