. The fatigue crack mainly initiates from the second phase particles and the interface between the second phase particles and matrix. The crack plane deflection in the process of crack propagation relates... propagation across a grain boundary. Key words: 2524 alloy; fatigue crack; initiation; propagation; microstructure ......
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......
Influence of microstructure stability on creep properties of single crystal nickel base superalloys TIAN Su-gui (田素贵)1, MENG Fan-lai (孟凡来)1, DU Hong-qiang (杜洪强)1, WANG Chun-tao(王春涛)1, SHUI Li..., China Received 28 July 2006; accepted 15 September 2006 Abstract: The influence of microstructure stability on the creep properties of single crystal nickel-based superalloys was investigated......

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......
