to improve the formability of spray deposited aluminum alloy preforms. Spray deposited SiCp/7090 Al-base composite was densified by temperature gradient cyclic pressing, and the density, hardness... with the height of 200 mm through the 315T hydraulic press. Key words: SiCp/7090 Al-base composite; temperature cyclic pressing; multi-layer spray deposition; densification ......
Preparation and properties of PAn/ATTP/PE conductive composites QIU Jian-hui(邱建辉)1, FENG Hui-xia(冯辉霞)1,2,3 1. Department of Machine Intelligence and Systems Engineering, Faculty of Systems... Nonferrous Metal Materials, Lanzhou 730050, China Received 10 April 2006; accepted 25 April 2006 Abstract: Polyaniline/Attapugite/ PE(PAn-ATTP/PE)composites containing particles with core-shell structure......
, and is up to the maximum of 172MPa when the vibration time is 30s. The phase structure of the bond region changes from the Zn-Al-Cu hyper-eutectic (η+(β+η)+(β+η+ε)) phases to Al-rich Al-base solid..., literatures about bonding of aluminum alloy and Al-MMCs with the aid of vibration technique havent been reported. In this study, the SiCp/ZL101A composites were bonded by the vacuum-free vibration liquid......
