Calculation of the Nucleation Temperature during Gas Horizontal Atomization Stage in the Spray Rolling of 7050 Aluminum Alloy

Abstract:

Spray rolling is a novel metallic semi-solid near-net-shape forming technology. This paper describes the qualitative influence of the key process parameters on the nucleation temperature during gas horizontal atomization stage in the spray rolling of 7050 aluminum alloy. The Newtonian heat transfer formulation has been coupled with heterogeneous nucleation, as well as the special solidification process. Results show that the droplet diameter has remarkable influence on nucleation temperature during spray rolling of 7050 aluminum alloy compared with that of wetting angle. The nucleation temperature approximately is 878K.
