There are still some technical and theoretical challenges to improve the alloy orientation and mechanical properties. In this research topic, the ferroalloy was selected as study subject with regard to its phase modification for the grain boundary. Based on the liquid diffusion of the metal in its processing, during which the orientation ability of the alloy was therefore enhanced, its microstructure and performance was improved. by the analysis of mechanical properties and microstructure changes in the structure for the alloy under different additives, the effects laws and mechanisms of alloy additives on its phase composition was clarified, and the mechanism about the enhanced alloy orientation by phase control and improved mechanical properties was illuminated. Based on further research on the effect of thermal deformation alloys on properties of sector structural changes, the enhancement mechanism for mechanical was also concluded. This study will be the preparation of high-performance alloys that could provide theoretical and experimental basis, which also has an important role in guiding further improve and optimize the design, production and application of high-performance ferroalloy. |
