Fine-Grained Bulk NiTi Shape Memory Alloy Fabricated by Rapid Solidifcation Process and Its Mechanical Properties and Damping PerformanceHongjie Jiang,Shanshan Cao,Changbo Ke,Xiao Ma,Xinping ZhangSchool of Materials Science and Engineering,South China University of Technology摘 要:A near-equiatomic NiTi shape memory alloy was fabricated by rapid......
in the aluminum matrix uniformly distribute but also dynamically influence the damping capacity of this alloy system. The Al–Pb alloy was prepared under a slow speed at solid–liquid temperature region, wherein high volume fraction of Pb in alloy could be obtained. The high volume fraction of Pb gives high overall damping capacity. The dislocation damping and interface damping theories are mainly dominated......

, and damping properties of a non-age-hardened Al alloy(5086) and an age-hardened Al alloy(7075) after friction stir processing(FSP). Microstructural analyses indicate that FSP led the grain refinement... particles in the 5086 alloy to break up. After being subjected to FSP with low rotation rate, the 5086 and 7075 alloys exhibited excellent mechanical and damping properties. Such improved properties......
