Study on the effects of the length and angle of inclined plate on the thixotropic microstructure of A356 aluminum alloy

Production of semi-solid feedstock of A356 alloy and A356-5TiB2 in-situ composite by cooling slope casting

“…The solidified strip and the morphology of A356 alloy on CS strip at exit end, poured at 60° angle is shown in figure 6. (2), reported elsewhere [11,12]. The variation of Grain size and S.F of α-Al phase of A356 alloy at different processing conditions is shown in figure 8.…”

“…In addition, Legoretta et al [10] developed a thorough understanding of the microstructural development of A356 alloy during the CS process and demonstrated the effect of process parameters on the CS cast feed stock. Taghavi and Ghassemi [11] investigated on the effects of the length (20, 30, 40, 50, 60 cm) and angle of inclined plate (20°, 30°, 40°, 50°) on the thixotropic microstructure of A356 aluminum alloy. Their results indicated that 40° and 40 cm condition is optimum inclined plate angle and length presenting the minimum grain size of 28μm and maximum shape factor of 0.70 with highest uniformity.…”

Effect of Pouring Temperature and Water Cooling on the Thixotropic Semi-solid Microstructure of A319 Aluminium Cast Alloy

“…Thixoforming and thixocasting are semi-solid processing (SSP) technologies combining the near-net-shape capabilities of die-casting and mechanical properties of forging 1,2 . Parts produced by thixoforming techniques are reported to have substantially higher quality than die-castings and lower cost than forgings 3,4 .…”

“…Cooling slope (CS) casting is one of the simplest and cheapest techniques used to produce ingots for thixocasting and rehocasting 1,3 . In this technique, molten alloy with a superheat temperature is poured on an inclined plate.…”

“…In CS casting, various parameters such as superheat (pouring) temperature, length, angle, vibration, water-cooling, inclined plate and mold materials can affect the final microstructure 1,3,8 . The effect of such parameters on the microstructural characteristics of both A356 and A357 Al alloys was extensively studied 1,3,[8][9][10][11] . In contrast, there is a lack of investigations studying the effect of CS casting process parameters on other cast Al alloys such as A319 and A390 alloys 12,13 .…”
