Interfacial Behavior of Micro-cellular Structural Al90Mn9Ce1/TiO2 Composite Prepared by Spark Plasma Sintering
With micron Al90Mn9Ce1 alloy powder clad by TiO2 nano-powder,a dense closed micro-cellular ceramics structure was fabricated.The alloy composite was filled inside by spark plasma sintering at temperature 793 K,and with the composite density of 98.2%.Micro-temperature area of Al90Mn9Ce1/ TiO2 matrix was simulated through ANSYS,and the macro lower temperature sintering mechanism was analyzed.The microstructure of the interface was investigated via scanning electron microscope,and the composition distribution of the interface was investigated via energy dispersive spectrometry.The formation and evolution of the interfaces were analyzed from plastic deformation,the interface creep,interfacial diffusion and other aspects.It was found that the application of DC pulse current has important effect on interfacial behavior and the performance of composite.
