History dependent creep of Ti-6Al-4V alloy

Metal Science, 1978
AbstractThe purpose of this short communication is to report the interesting observation that the steady state creep rate (SSCR) of, Ti-6Al-4V alloy is history dependent. Temperature increment tests yield different results from temperature decrement tests.

Hydrogen-Induced Wear of Ti–6Al–4V Alloy

Advanced Materials Research, 2012
The effects of hydrogen on friction and wear properties of Ti–6Al–4V alloy sliding against GCr15 steel were investigated through dry sliding friction and wear tests in atmosphere at room temperature. Wear mechanism was determined by studying the morphology and chemical element of worn surface using SEM and EDS.

Powder injection molding of Ti–6Al–4V alloy

Journal of Materials Processing Technology, 2006
Abstract An improved wax-based binder was developed for the powder injection molding of Ti–6Al–4V. A critical powder loading of 72 vol% and a pseudo-plastic flow behavior were obtained by the feedstock based on the binder. The injection molding, debinding and sintering processes were studied.

Ion implantation of surgical Ti6Al4V alloy

Materials Science and Engineering, 1985
Abstract Ion implantation of nitrogen into surgical Ti6Al4V alloy (where the alloy composition is given in approximate weight per cent) dramatically improved the corrosive wear performance of the alloy. Experiments made use of a special apparatus designed to simulate pertinent chemical and mechanical aspects of the sliding interface between the ...
