Cavitation-induced erosion has been examined in Ti-6A1-4V in the mill annealed, solution-treat and aged, and beta annealed conditions. Weight loss data show only small differences between heat treatments with the solution-treat and aged microstructure exhibiting the lowest weight loss rates. Sequenti...

Pins of the Ti–6Al–4V alloy are used in both solution treated and aged conditions. The objective of the study is to understand the influence of thermo-mechanical mixed layers (TMML), which form on the surface of the worn material during the course of the wear test, on the friction ...
A sheet of textured titanium alloy Ti-6Al-4V was examined after various solution treatments to ascertain the effect of heat treatment upon texturing, microstructure, and mechanical properties. Specimens were solution treated between 1400 and 1800 F for 1/4 hour, water quenched, then aged at 1000...
Dynamic indentation (DI) tests using spherical projectile have been carried out on solution treated and aged (STA) Ti–6Al–4V alloy at ambient conditions ... A Kumaraswamy,VV Rao - 《Materials Science & Engineering A》 被引量: 2发表: 2011年 Effect of Microstructure on the Fatigue Behavior ...
Conventionally forged Ti–6Al–4V alloy processed to a solution-treated and over-aged condition was used for both programs. Temperatures for the TP-2 were: room temperature, 175, 230, 290 and 345 °C. An increase in stress ratio and temperature lowered the transitional stress intensity factor ...
