Influence of solution treatment on microstructure and properties of in-situ Mg2Si/AZ91D composites PENG Lei, CHEN Gang, ZHAO Yu-tao, HUANG Kang, SHAO Yang School of Materials Science and Engineering, Jiangsu University, Zhenjiang 212013, China Received 26 October 2010; accepted 11 April 2011 Abstract: The influence of solution treatment on the microstructure and properties of Mg2Si/AZ91D......
to various microstructure features. The Zn- and Al-rich phases exist in the middle brazing seam regions. However, two interface layers, CuZn3 and Al2Cu are formed on the Cu side when the Al content... the microstructure of the filler metals and the morphology of the brazing interface, respectively. Shear tests were conducted using a universal tensile test machine. The microhardness distribution......

using a Hopkinson bar. The relationship between the interfacial characteristics and the dynamic compressive behavior was investigated. The results indicate that the interface characteristics... obviously if the suitable interface reaction occurs. The failure occurs by shear and the fibers split longitudinally if there is no interface reaction or a little reaction; in contrast, holistic failure......

and the nucleation sites of microcrack at the primary α phase boundaries also decrease, the impact toughness value is effectively improved. The microcracks of lamellar microstructure are located on α/β interface... microstructure is dependent on the size, direction of colony. The crack path deflects at grain boundaries, colony boundaries, or arrests and deviates at α/β interface because of crisscross α lamellar......
