When the best part of Christmas is playing Santa Claus and helping poor, elderly and lonely people. Take Away English talks about giving a helping hand.

本研究针对高压压铸(HPDC) AlSi10MnMg合金中冷隔缺陷(cold flakes)导致力学性能下降的行业难题，系统探究了铁含量(0.1-0.2 wt%)和压射套加热工艺对缺陷形成的影响。通过微观结构表征和力学性能测试，发现增加铁含量可降低半固态合金固相分数从而抑制冷隔缺陷，但会降低基体合金性能；而压射套加热 ...
