COMPARATIVE-ANALYSIS OF STRUCTURE AND PROPERTIES OF TITANIUM-ALLOYS IN REGARD TO MOLYBDENUM AND ALUMINUM EQUIVALENTS

A comparative consideration of titanium alloys manufactured in Russia, USA, Europe, Japan, and China is given in diagram with coordinates al uminum equivalent - molybdenum equivalent. With a comparative narrow p redetermined range of molybdenum equivalents, the room-temperature alu minum-equivalent dependence of the strength of alpha and pseudo-alpha alloys could be described by the following regression equation: UTS, M Pa = 326 + 60 [Al](eq). With comparable values of aluminum equivalent the highest strength properties of the annealed and of the seed titani um alloys are observed when the molybdenum equivalents are 10 - 11% an d 11 - 13%, respectively.
