and external pressure have significant influence on the pull strength at the bonding interface. Cross-sectional microscopy of the bonding interface indicates that the packages bonded with relatively low... conditions, the packages were cross-sectioned and polished with a polisher (Buehler, Inc., model 60-1950-160) to reveal the bonding interface. The cross-section was then observed under a microscope (Nikon Inc......

in the 45# carbon steel substrate diffuses into the high Al bronze coating, a metallurgical welded interface forms, and interface bonding strength reaches 346.8 MPa. The content of Fe-rich K phase increases, and the hardness of the coating surface reaches 301.3HV. Al in the high Al coating diffuses onto ZQAl9-4 aluminum bronze substrate, and interface bonding strength is obviously improved......
A novel diffusion model considering curvature radius at the bonding interface in a titanium/steel explosive clad plateHai-tao Jiang1,Qiang Kang11. National Engineering Research Center for Advanced..., and electron-probe microanalysis. Carbon atoms within the steel matrix were observed to diffuse toward the titanium matrix and to aggregate at the bonding interface at 850°C or lower; in contrast, when......
that in M40/5A06Al composite. Generally, a weak reaction between fibers and aluminum results in weak bonding at their interfaces, so interface bonding in M40/5A06Al composite should be weaker than that in M40/6061Al composite. The variation of interface bonding in the composites could affect their thermal expansion behavior. Fig.1 Optical microstructures of Cf/Al composites: (a) M40/6061Al; (b......
