Study of the melting of FeSi interstitial alloy films by SMM

This study utilizes the statistical moment method to investigate the effects of high temperature and pressure on the structure and melting process of Fe thin films and FeSi interstitial alloy thin films with a BCC structure. The theory is developed and validated through calculations with Fe films, then extended for application to FeSi films. When the number of layers increases to 200, corresponding to a film thickness of 70 nm, the melting temperature approaches that of the bulk material. The research results indicate that the addition of Si to FeSi films causes significant changes in melting temperature and structure, reducing the material's heat resistance.
