HEAT TREATMENT OF ALUMINIUM ALLOY - HEAT TREATMENT OF ALUMINIUM ALLOY  (Paperback, Ashok Kumar,Dipak Kumar Banerjee)

Aluminium alloys have been in use since 1940. The development of light weight Al-Si alloys led to its usage in wear resistant components. The property of light weight and good thermal conductivity of hypoeutectic, hypereutectic alloys such as A357 and A380 enabled automobile industries to manufacture Al-Si cylinder blocks by the method of die-casting. The cast A357 alloys with improved mechanical properties, low porosity levels, good dimensional accuracy, dimensional stability and good surface finish can be ranked as number one with respect to dimensional stability, fluidity, pressure tightness and weldability.
