MECHANICAL PROPERTIES OF TITANIUM ALLOYS AS A FUNCTION OF HEAT TREATMENT AND SECTION SIZE

摘要

The mechanical properties of 6A1-4V, 6.5Al-3Mo-lV, and 6M6-3A1 titanium alloys were obtained as a function of section size and heat treatment. Sections of 2-, 3-, 4-, and 6-inch diameter rounds were studied, with each alloy being subjected to two solution temperatures, followed by three aging temperatures. Tensile and impact data were obtained in all cases. As a result of the findings, optimum heat treatment for the investigated conditions was established for each alloy. Other factors, such as speci¬men location, directionality, and microstructure, are discussed.
