Additional Fracture and Strength Test Results for A723 Steel and 38644 Titanium

Abstract

Four types of additional mechanical test results are described for high strength steel and titanium alloys, as a continuation of previous work. 1) The effects of elevated temperature on the circumferential orientation tensile properties of titanium and steel cylinders are described. 2) A comparison is presented of strength and fracture toughness results from two titanium ingots. 3) The fatigue lives of notched bend specimens of titanium are measured and compared with calculated fatigue lives for steel. 4) The effects of elevated temperature cycles and plasma spraying process on the strength of steel are presented. Keywords: Fracture toughness; Mechanical properties; Elevated temperature; Fatigue crack initiation; Pressurized cylinder.
