EFFECT OF HEAT TREATING VARIABLES AND ELEVATED TEMPERATURES ON THE MECHANICAL PROPERTIES OF HIGH OXYGEN 6A1-4V TITANIUM ALLOY

Abstract

The effect of 25 F variation in solution heat treatment and 20 F variation in aging temperatures upon the mechanical properties of a 0.20 to 0.25% oxygen Ti 6Al-4V heat were determined. As a result of tests yield and ultimate strength variations between 164.2 to 176.1 ksi and 176.4 to 191.0 ksi, respectively, with no significant variation in ductility was found. Elevated temperature mechanical properties tests showed that the room temperature strength advantage found in the high oxygen Ti 6Al-4V diminished as temperatures rose to 750 F where the advantages began to disappear. Stress stability tests conducted at 750 for 1000 hours in the presence of 50 ksi stress indicated the high oxygen Ti 6Al-4V to be stable under these conditions. (Author)
