Application of shortened heat treatment cycles on A356 automotive brake calipers with respective globular and dendritic microstructures

Author: Moller, H ; Govender, G ; Stumpf, WE Date: Sep 2010 The conventional casting alloy A356 is probably one of the most popular alloys used for semi-solid metal (SSM) forming. This is due to its high fluidity and good castability. This alloy can be heat treated alternatively to the T4, T5 or T6 ... Read more
Characterization of surface liquid segregation in SSM-HPDC aluminium alloys 7075, 2024, 6082 and A201

Author: Moller, H ; Curle, UA ; Masuku, EP Date: Sep 2010 Semi-solid metal (SSM) processing is a unique manufacturing method to produce near-net shape products for various industrial applications. The nature of the SSM slurry (with solid spherical grains suspended in a liquid), makes it susceptible ... Read more
Influence of surface liquid segregation on corrosion behavior of semi-solid metal high pressure die cast aluminium alloys

Author: Masuku, EP ; Moller, H ; Curle, UA ; Pistorius, PC ; Li, W Date: Sep 2010 The aim of SSM forming is to obtain a semi-solid structure (which is free of dendrites) with the solid present in a near spherical form. The nature of the SSM slurry (with solid spherical grains suspended in a liquid), makes it susceptible ... Read more
Semi-solid near-net shape rheocasting of heat treatable wrought aluminum alloys

Author: Curle, UA Date: Sep 2010 Flexibility of the CSIR-RCS, induction stirring with simultaneous air cooling process, in combination with high pressure die casting is successfully demonstrated by semi-solid rheocasting of plates performed on commercial 2024, 6082 and 7075 ... Read more
Semi-solid rheocasting of grain refined aluminum alloy 7075

Author: Curle, UA ; Govender, G Date: Sep 2010 Near-net shape rheocasting with the Council for Scientific and Industrial Research Rheo casting system(CSIR–RCS) and a high pressure die casting machine was successfully performed on Al–5Ti–1B grain refined aluminum alloy 7075. Grain refinement ... Read more
Wear of semi-solid rheocast SiCp/Al metal matrix composites

Author: Curle, UA ; Ivanchev, L Date: Sep 2010 Rheocasting of plates in Al alloy 359 reinforced with SiC at 11%, 27% and 50% (volume fractions) exhibits the capability of the council for scientific and industrial research-rheocasting system (CSIR-RCS) in rheo-processing and high pressure ...
