摘要
Abstract
In this study,TC4 alloy ingots were prepared using surplus titanium plate,titanium chip,sur-plus titanium billet and high-purity raw material.The suitability of centrifugal casting technology to dif-ferent scrap titanium was systematically analyzed in terms of composition,microstructure and hardness.The results show that the contents of N,O and H elements in the four ingots satisfy the requirements of GB/T6614-2014.However,due to the physical and chemical reactions that occur in scrap titanium ma-terials during different hot forming processes,they can have an important influence on the solidification process of TC4 alloys,resulting in some differences in microstructural and mechanical properties of in-gots.In addition,the hardness of the four ingots meets the requirements of GB/T6614-2014,which fur-ther confirms that the centrifugal casting technology can be applied to the recovery of scrap titanium.After heat treatment,the microstructure homogenization of 4# alloy was significantly improved,and the abnormal areas disappeared.The maximum hardness value of 32.5 HRC was obtained for the samples treated by vacuum argon quenching process Ⅰ.关键词
