alloy material for tissofusione, process for the preparation of semi molten alloy material and process for tissofusione

摘要

it described a material aluminium alloy for tissofusione.in a thermal imaging for differential thermal analysis of this material in the aluminum alloy for tissofusione established the correlation e1? l2 between a peak value e1 of the first section endotermica of angle generated by the fusion of a eutettico and a peak value e2 of a second section of the corner caused by the endothermic fusion of a segment having a melting point higher thanthe point eutettico.a liquid phase produced by the fusion of the eutettico has a large latent heat, because the peak value e1 of the first endothermic section of angle is higher than the peak value l2 of thein the second section of the corner in an endothermic material aluminium alloy eutettico semifuso derived from material aluminium alloy for tissofusione.as a result, in the stage of solidification process for tissofusione a liquid phase produced by the fusion of a eutettico is fed enough around a solid phase at wk 12 wk 12 wkon the solidification and the withdrawal of the solid phase and then solidified. therefore, it is possible to produce a fusion flaws as empty of the micron order.
