The interface characteristics and microstructure formation of TA2-5083 composite plate after explosive welded were studied. Optical microscope electron used to analyze the intermetallic compounds. Furthermore, ANSYS/AUTODYN was adopted calculate simulated by smooth-particle hydrodynamics (SPH) method. results show that most molten metal in wave front stays wave-waist region. There a relative ve...

The heat treatments have been designed to vary the matrix microstructure in P/M processed SiC reinforced 7xxx Aluminum alloys to determine the effects of matrix microstructure, interface behavior on the mechanical properties. Smooth tensile, notched bend tests were performed. The results conclude that the clustered regions have been observed as preferred initiation sites in both tensile and not...

We studied the shear deformation of a laminar Al-Cu composite with (100) and (110) interfaces perpendicular to lamellae in comparison pure single crystal Al Cu at strain rates 109 s−1 108 different initial pressures range from −3 GPa +50 GPa. The results molecular dynamics (MD) for plasticity initiation are generalized by means an artificial neural network (ANN) trained MD data interface, rate ...

The scientific importance of nanocomposites are being increased due to their improvedproperties. This paper is divided into two parts. First, Al-Al2O3 nanocomposite wasproduced by using ball milling technique followed by cold compaction and sintering.Microstructure and morphology studies were done through SEM, TEM, and EDX anal-ysis on the produced powder. The mechanical properties of the produ...
