Abstract:
Among the various methods that use to produce semisolid feedstock materials, casting by inclined plate is one of the most effective and low cost that requires little equipments. Length, angle and material are main parameters that affect final microstructure of pieces casted by inclined plate. In this study, in specific length and at different angles (10˚, 20˚, 30˚ and 40˚) the effect of changes in slope material on characteristic of flake graphite was investigated. A large number samples were prepared under differentconditions and microstructure analysis by SEM microscope were performed on samples and for closerstudy images were evaluated by Clemex and MIP image analysis software. Results shown the angle at which can achieve optimize microstructure changes with variation in slope material, that this angle for graphite and steel plate is 30˚ and 20˚, respectively. Use of inclined plate in casting reduces length and thickness of flake graphite. Also for specimens casted at 30˚ on graphite plate, radius of tip curvature for flake graphites is larger than specimens casted at 20˚ on steel plate and without inclined plate that reduces stress concentration on tip of flakes
