Abstract
Field emission scanning microscopy(FESEM) and energy-dispersive X-ray spectroscopy(EDXS) were used to study the morphology and composition of secondary phase precipitations in induction-melted higher manganese silicide(HMS).Striations of the secondary phase were observed in individual HMS crystals with an average interval of 5-30 μm and a thickness of ~30 nm.The chemical composition of the striations was examined and found to be MnSi,which was observed as an amorphous phase by high resolution transmission electron microscopy(HRTEM).The crystal structure of HMS was determined by selective area electron diffraction(SAED) and the results indicated a single Mn4Si7 phase in the as-prepared material and no other incommensurate HMS phases were found.After ball milling and hot pressing many defects and stress fields were observed in the HMS by transmission electron microscope(TEM),which differentiated substantially from the morphology of the as-melted HMS.
