In modern engineering low-density composites plays a vital role of which magnesium alloys are very effective due to its high strength with better corrosion resistance and neat cast ability. In this work a micron sized Boron carbide ceramic (B4C) of about 100 microns is diffused as a reinforcement with AZ91 for preparing a magnesium metal matrix composite (MMMC) through stir casting route. A modified pit furnace setup is used for doing stir casting with varying volume fractions of 0％ and 3% of boron carbide for doing the composites. Furthermore mechanical and metallurgical properties like Tensile test is made through universal testing machine, Micro-hardness through Vickers hardness tester and Micro structure through Optical Microscopy is done for investigation.

Abstract This work investigates the importance of the microstructure of boron carbide for initiating inelastic deformation under impact conditions. Simple loading resulting from a flyer plate impact geometry is used to illustrate the importance of microstructure for the well-controlled and easily instrumented experimental geometry. A second set of simulations is performed on a miniaturized impact geometry to investigate the importance of the microstructure for the early stages of semi-infinite penetration for impact velocities between 0.9 km/s and 1.9 km/s. The effect of the microstructure is more pronounced for the flyer plate impact geometry.

ABSTRACTSemiconducting boron carbide overlayers, formed from the decomposition of orthocarborane and metacarborane have been studied by angle resolved photoemission. The incurrence of surface photovoltage and the photovoltaic process, from the photoemission experiment, reveal band offsets in the orthocarborane multilayer configurations that are invereted relative to single layer configurations. Defect induced gap states which trap charge at the heterostructure interface is used as one explanation of these results. The role of defects is also used to help illuminate why opposite semiconducting type materials are formed from the decomposition of isomer carborane molecules.
