摘要：
Metallographic evidence is presented for existence of inverse surface macro-segregation in a HPDC AM60 Mg-alloy. The process conditions that facilitate the inverse surface macro-segregation are identified, and the effects of macro-segregation on the low and high cycle fatigue behavior of the HPDC alloy are studied.
