The influence of transition metals (Ni and Zn) on the formation, morphology, thermal stability long-period stacking ordered (LPSO) phases in Mg97Er2Ni1 Mg97Er2Zn1 alloys was investigated. In as-cast state, both consist α-Mg LPSO phases. Heat treatment at 540 °C for 20 h dissolves block-like lamellar into matrix alloy, with reprecipitating during subsequent cooling from to 400 °C. Comparative analysis shows that Ni significantly enhances phase compared Zn. favors formation block-shaped phases, while Zn facilitates precipitation within matrix. alloy exhibits an exceptionally high melting temperature 605 °C, highest reported phase. Additionally, heat 500 100 preserves area fraction h, grains grow without dissolution or structural transformation their 18R-type configuration. These findings provide valuable insights role alloying metal elements controlling morphology offering pathways tailoring Mg-based alloys.
