. For the sake of suppressing the interference of alloying elements on the microstructure analysis, pure PM Al was fabricated via the same process as a reference to study the distribution of Al2O3...: 10.1016/j.jmrt. 2020.04.087. [30] BALOG M, POLETTI C, SIMANCIK F, WALCHER M. The effect of native Al2O3 skin disruption on properties of fine Al powder compacts [J]. Journal of Alloys and Compounds, 2011......
炉内的氧气和水汽,净化,抑制了铝的再氧化.随着温度的继续升高,又发生如下反应:3) 3Mg+Al2O3→3MgO+2Al母材表面Al2O3被还原,使表面活化,易于钎料的流动,由此可知,镁元素实际上起了溶剂的作用[70].常用的Al-Si-Mg系钎料有4N04,4104,4004等,由于此钎料中Mg含量较低,从而钎料的熔化温度较高,主要用于钎焊熔化温度较高的铝合金,如3003,6063等铝合金.此外......
