Modeling Metal Droplet Sprays in Spray Forming

Heat Transfer and Fluids Engineering, 1995
Abstract Spray casting is a process whereby a molten metal stream is atomized and deposited on a substrate. The rapid solidification of the metal droplets gives rise to a fine grain structure and improved material properties. This paper presents a simulation for the fluid and thermal interaction of the fluid and droplets in the spray and

Cold Spray Forming of Inconel 718

Journal of Thermal Spray Technology, 2012
Inconel 718 was cold spray formed to a 6-mm thickness on an 8-cm diameter aluminum alloy tube using Sulzer Amdry 1718 powder and the Plasma Giken PCS-1000 cold spray system. The effects of spray particle velocity and post-spray heat treatment were studied. Post-spray annealing was performed from 950 to 1250 °C for 1-2 h.

Porosity in Spray-Formed Materials

Materials Science Forum, 2007
Porosity in spray-formed materials is an important issue, but the formation of porosity is not completely understood. Many experimental results and some theoretical models have been presented in the past. Nevertheless, the prediction of porosity in a deposit is still not possible today.

Spray-formed high-aluminium bronzes

Materials Science and Engineering: A, 2008
Abstract Unlike standard wrought aluminium bronze, high-performance wrought aluminium bronze with an aluminium content of more than 12 wt.% and additions of iron, cobalt and manganese is difficult to produce by continuous casting. This type of wrought aluminium bronze is much easier to produce by spray forming.

Spray forming of metals

2004
Spray forming is an advanced process route to produce near-net-shaped preforms from metallic materials. As it combines the main advantages of the classical processes of metal casting and powder metallurgy, its products are characterized by extraordinary material properties.

Spray-forming Aluminium Billets

1996
In the aluminium billet spray-forming process a molten metal stream is first atomised by high speed gas jets and is then deposited onto a rotating circular metal collector plate. The collector is positioned some distance from the atomiser, to allow partial solidification of the spray before impact, and is withdrawn slowly downwards as the primarily ...

The Dynamics of Spray-Formed Billets

SIAM Journal on Applied Mathematics, 1995
Summary: A model is developed to describe three-dimensional transient growth of spray-formed aluminium billets. Approximation via an averaging method reduces the problem to a single quasilinear partial differential equation describing the ``slow-time'' axisymmetric growth of the billet crown under the influences of billet withdrawal and time-averaged ...

Spray Forming Titanium Alloys using the Cold Spray Process

International Thermal Spray Conference, 2005
Abstract Development of new, low-cost methods for spraying near net shapes of Titanium and Titanium alloys is critical for many industries and applications. Direct fabrication technologies would have an impact on many industries because of the potential to quickly manufacture complex parts or additive features with minimal waste. However,
