HIGH STRENGTH TITANIUM ALLOY, PRODUCT MADE THEREFROM AND METHOD FOR PRODUCING THE SAME

摘要

A high strength titanium alloy superior in decoration properties and appearance, hardly subject to scratching and denting, having good machinability, and especially useful as a raw material for various types of accessories, products such as described above that are made of the same alloy and a useful method for producing such products. These are achieved by a titanium alloy containing 0.20-0.8 mass percent of Fe and 0.20-0.6 mass percent of O, respectively, or 0.2-1.0 mass percent of Fe, 0.15-0.6 mass percent of O, 0.20-1.0 mass percent of Si, respectively, with the remaining of Ti and unavoidable impurities. In addition, various types of products requiring strength are produced through a process comprising hot forging the alloy under a condition in which a raw material temperature is higher than beta transformation temperature minus 200 DEG C, and thereafter cooling the alloy so forged.
