; 文献标志码:A Strengthening mechanism and dynamic recrystallization behavior of TiC/Cu-Al2O3 composite YANG Zhi-qiang1, LIU Yong1, 2, TIAN Bao-hong1... Province, Luoyang 471023, China) Abstract: The TiC/Cu-Al2O3 composite was prepared by vacuum-pressed and internal oxidation sintering. The microstructures were observed and the main strengthening......
Deformation behavior and mechanisms of Ti-1023 alloy BAO Ru-qiang(鲍如强), HUANG Xu(黄 旭), CAO Chun-xiao(曹春晓) Beijing Institute of Aeronautical Materials, Beijing 100095, China Received 15 June 2005...; Abstract: The deformation behavior and mechanisms of Ti-1023 alloy were studied......
Cdis is the equation coefficient and n6 is a material constant. In consideration of the similar strengthening mechanisms of the 6xxx-series aluminium alloys and in the interest of simplicity.... Transmission electron microscopy was used to observe the precipitate distribution and to thus clarify strengthening mechanism. A new model was established to describe the strengthening of AA6082 by HFQ......
formation and strengthening mechanisms of a dual-phase nanocrystalline CrMnFeVTi HEA were investigated. It is found that CrMnFeVTi HEA exhibits high compressive strength and hardness, and the solid... and compressive strength of the above HEA. So, a non-equiatomic CrMnFeVTi6 HEA was designed in this work. In order to develop successful engineering alloys, various strengthening mechanisms, such as solid......
