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
Effect of heat treatment on the properties of laser-beam welded rheo-cast F357 aluminum

Author: Theron, Maritha ; Knutsen, RD ; Ivanchev, LH ; Burger, HP Date: Feb 2012 Semi-solid metal rheo-cast F357 aluminum plates were joined by autogenous Nd:YAG laser welding and were welded in either the as-cast (F) condition, T4 temper or T6 temper condition. The weldability of this age-hardenable Al–7%Si–0.6%Mg casting ... Read more
The effect of natural pre-ageing on the mechanical properties of Rheo-High pressure die cast aluminium alloy 2139

Author: Chauke, L ; Daswa, P ; Möller, H ; Govender, S Date: Jul 2015 Near-net shape casting of wrought aluminium alloys has proven to be difficult due to hot tearing. The Council for Scientific and Industrial Research (CSIR) has successfully processed wrought aluminium alloy 2139 into plate castings using the ... Read more
Influence of liquid surface segregation on the pitting corrosion behavior of semi-solid metal high pressure die cast alloy F357

Author: Moller, H ; Masuku, EP Date: 2009 Semi-solid metal processing results in liquid segregation at the surface of the components. The pitting behaviour of this surface layer of semi-solid metal processed alloy F357 was compared with the centre (or bulk) of cast plates in 3.5% ... 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
Natural and artificial aging response of semi-solid metal processed alloy A356

Author: Möller, H ; Govender, G ; Stumpf, WE Date: Sep 2008 The heat treatment cycles that are currently applied to semi-solid processed components are mostly those that are in use for dendritic casting alloys. These heat treatments are not necessarily the optimum treatments for non-dendritic ... Read more
T6 heat treatment of semi-solid metal processed alloy A356

Author: Moller, H ; Govender, G ; Stumpf, WE Date: 2008 Semi-solid metal (SSM) processing is a unique manufacturing method to produce near-net shape products for various industrial applications. The aim is to obtain a semi-solid structure free of dendrites (which are formed by conventional liquid ... Read more
