Title

EFFECT OF TEMPERATURE ON THE MICROSTRUCTURE OF SEMI-SOLID CASTING IN COOLING SLOPE METHOD

Pages

  55-63

Abstract

 The COOLING SLOPE (CS) method is one of the semi-solid methods that the molten alloy with a suitable amount of superheat is poured on a COOLING SLOPE for achieving fine and non-dendritic structure. This paper discusses the effect of temperature on the final microstructure of A356 aluminum alloy. These temperatures are CASTING temperature, mold temperature and CS plate temperature. The dendritic primary phase in the conventionally cast A356 alloy has transformed into a nondendritic one in cast ingots on a cooling plate at 5 different CASTING temperature, 3 different mold temperature and also two conditions of using a cooling system or without it. It was found that the microstructure gets finer decreasing CASTING temperature to 6250C. The CS used in this study, which also controls the surface temperature, has a significant effect on the microstructure. This effect is 22% decrease on average grain diameter and 8.5% increase on the shape factor at the weakest case. Also increasing the mold temperature up to 2000C causes globularity and appropriate distribution of a-Al particles.
