INVESTIGATION OF CREEP BUCKLING OF COLUMNS AND PLATES. I. ELEVATED TEMPERATURE PROPERTIES OF THE TEST MATERIAL Ti-7Al-4Mo TITANIUM ALLOY
Technical Report
·
OSTI ID:4161535
As a first phase of an investigation of the creep buckling of columns and plates, materials properties tests were conducted on Ti-- 7A1-4Mo Titarium Alloy in both the annealed and heat treated conditions. Heat treatment to obtain optimum creep penformance was 1450 deg F-1 hr, FC to 1050 deg F, AC; 1050 deg F- 24 hr, AC. A new technique for the collection of compression creep data from sheet specimens was developed in which both the short time stress-strain properties prior to creep and the creep data itself are autographically recorded. Short time tests were conducted at room temperature, 750, 550, and 950 deg F. Compressive creep data were collected at 850 and 950 deg F (auth)
