Materials and Methods In order to investigate the effect of Er additions on hypoeutectic Al-Si-based alloys, a reference and two modified alloys were cast.
The widely diffused Al-7Si-0.3Mg alloy (UNS 13560, corresponding to ANS A356.0, which composition limits are listed in Table 1) was selected as reference material.

The decreasing trend of the normal force distribution at ratios higher than the critical ratio might be due to some kind of changes in the dominating material removal mechanisms at such grinding conditions.
