| Abstract | ||
| The objective of this paper is to study gating system design effect onAl-5%Mg alloy Microstructure Measurement (By Jeffrece's Method) and freezing range, two sand mould were made with different gating systems Practicality (in Runner length & Runner depth) to study the effect on freezing ratio & Microstructure, a VBA Program was bulid because Most of result are stored in Microsoft Excel 2007Spread Sheet in which Calculation of Grain size were performed for many specimens ,Results shown that the gating system with runner length 2.5 cm and taper sprue gave better results than gating system with a 4cm runner's length and cylindrical sprue . | ||
