Abstract: An integrated, multiphysics numerical model has been developed through the joint efforts of the University of Oxford (UK), University of Bremen (Germany) and Inasmet (Spain) to simulate the spray forming process. The integrated model consisted of four sub-models: (1) an atomization model simulating the fragmentation of a continuous liquid metal stream into droplet spray during gas atomization; (2) a droplet spray model simulating the droplet spray mass and enthalpy evolution in the gas flow field prior to deposition; (3) a droplet deposition model simulating droplet deposition, splashing and re-deposition behavior and the resulting preform shape and heat flow; and (4) a porosity model simulating the porosity distribution inside a spray formed ring preform. The model has been validated against experiments of the spray forming of large diameter IN718 Ni superalloy rings. The modelled preform shape, surface temperature and final porosity distribution showed good agreement with experimental measurements.

TL;DR: In this paper, a comparison has been made between samples manufactured by conventional processing (casting and forging ) and by spray forming, showing that both the carbide size and carbide type had little effect on wear rate when tested in the quenched and tempered condition.

TL;DR: In this article, a spray forming rapid solidification technology was used to produce a Zn-rich Al-11.3Zn-2.65Mg-1Cu alloy, which was then processed by hot extrusion and heat treatment to T6-temper condition.

TL;DR: In this article, a spray-formed Al 86 Si 0.5 Ni 4.06 Co 2.94 Y 6 La 0.94 Co 2.5 amorphous matrix nanocomposite plate with a rough diameter of 200mm and a maximum thickness of 12mm has been prepared by spray-forming.

TL;DR: In this paper, the microstructure and hardness of spray-deposited bulk materials were characterized in terms of microstructures and hardness, showing that the hardness indentations in Al-Cu-Fe alloy introduced cracking in the material, whereas the Sn-rich areas inhibited the crack growth.
