Hydrogen-based Pore Formation in Aluminum Alloy Castings

从汽车行业增加气孔使用的角度来看，控制近净形状铝合金铸件中的气孔形成是至关重要的，因为气孔的存在会严重破坏承受循环载荷的部件的性能。与气孔相关的缺陷导致的生产率降低以及过度设计许多部件的需要也增加了成本，进一步侵蚀了铸铝产品的商业采用率。

The control of pore formation in near-net-shape aluminum alloy castings is critical from the standpoint of increasing their use in the automotive sector as the presence of pores can act to seriously undermine the performance of components subject to cyclic loading. Reduced productivity associated with pore-related defects and the need to over-design many components also adds cost, further eroding increased commercial adoption of cast aluminum products.
