Comparative development between systems of formation and incorporation of defects in aluminum castings

ABSTRACT The present work is a comparative study between two filling systems, one called conventional and another called constrict. The objective of this work is to evaluate the performance of the systems in the formation and incorporation of defects (oxides and air bublles) in aluminum cast part (plate), in no bake process. In this study, we used numerical simulation software (MAGMASOFT), X-ray test, tensile test, optical microscopy and scanning electron microscopy (SEM). In comparison, the samples of conventional system showed greater tendency to the formation and incorporation of defects and lower mechanical resistance, showing better performance of constrict system.
