Abstract Scope |
Ti is the most preferred element as a grain refiner but grain refinement mechanism and performance are matter of debate because of fading effect. Due to the density difference, Ti compounds that will form nucleation centre collapse to the bottom of the crucible and lose the efficiency. In this study, correlation between Ti-grain refinement process and bifilm precipitation by Ti compounds was investigated. Primer and seconder A356 alloys were used. After the addition of grain refiner, melt quality chance was monitored collecting RPT sample every 8 minutes. To determine the mechanical properties, tensile samples were cast into the die and sand moulds at same period. It was observed that melt quality increased in time. Differences of mechanical properties were noteworthy. |
