Title:
TITANIUM ALLOY COMPOSITE POWDER CONTAINING CERAMICS AND MANUFACTURING METHOD THEREOF, AND DENSIFIED TITANIUM ALLOY AND MANUFACTURING METHOD THEREOF USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/152359
Kind Code:
A1
Abstract:
Disclosed are a high-quality titanium alloy powder and titanium alloy material formed by means of the powder method with titanium alloy scrap and titanium alloy ingots as a raw material; also disclosed is a method of manufacturing the same. A raw titanium alloy material is hydrogenated to form hydrogenated titanium alloy, which is crushed and sieved to obtain a hydrogenated titanium alloy powder. A ceramic powder selected from SiC, TiC, SiOX, TiOX (here, the subscript x is a real number in the range of 1 ≦ x ≦ 2) and Al2O3 is added, and a mixture of the hydrogenated titanium alloy powder and the ceramic material powder undergoes dehydrogenation treatment, resulting in the titanium alloy composite powder. Further disclosed are a dense titanium alloy material obtained by HIP treatment subsequent to CIP treatment of the titanium alloy composite powder, and a manufacturing method thereof; and a dense titanium alloy material obtained by HIP treatment after encapsulating said titanium alloy composite powder, and a manufacturing method thereof.
