slurry at low solid fractions. A laboratory extrusion system was used to fabricate aluminum rods with the diameter of 12 mm. The semi-solid metal process used in this study was the gas induced semi..., and mechanical properties of extruded samples were investigated. The results show that the plunger speed and solid fraction of the semi-solid metal need to be carefully controlled to produce complete......

One approach for the near-net- shape casting of wrought aluminum alloys is the application of semi-solid metal processing......
-step reheating process can restrain the coalescence of grains to a certain extent, and thus refine the grain size and promote the grain spheroidization. Key words: semi-solid metal...; 1 Introduction The semi-solid metal forming technology has numerous advantages, such as high density of castings, prolonged die life, low forming......
, and heat treated because of these defects[1-4]. To improve the quality and properties of the die casting process, semi-solid metal technique has been introduced. A lot of semi-solid die casting studies have reported that using semi-solid die casting helps to improve the properties and increase the quality of die casting parts[5-7]. Semi-solid metal forming using the rheocasting route can provide......
