By means of OM, EDS, SEM and TEM, the effect of microstructures of AA3003 aluminum alloy foils on specific capacitance was investigated . The results show that
Based on the theory derivation and analysis of practice surveying data, the best surveying distance method and the best surveying distance according to the chosen distance gages are determined. Accord
<正>The high performance magnesium alloy was investigated by adding B2O3 in magnesium and magnesium alloys. Experiments include adding B2O3 in Mg, Mg-Al and Mg-
Heredity of microstructure in AlTiC master alloy, grain refiners, was analyzed. It is found that, for morphologies and distributions of TiC particles, there are
