Additional data disclose the effects of the identity and quantity of gas, the temperature range of freezing, and the freezing rate upon the amount and distribution of porosity in light metal castings.doi:10.1007/BF03397707Whittenberger, E. J....
Here is what a few of our clients had to say about ourAluminum Casting and Metallurgyclass. Very good coverage. The fact that the presenters are ex-foundrymen makes this an excellent course. Ray FranksHTCI Everyone in the Aluminum industry could benefit from this class ...
Also, placing liquid metal in a vacuum may cause its entrained bifilms to expand, enhancing their buoyancy and therefore their floatation to the surface of the melt. In this work, a casting from an A356 Al alloy was allowed to solidify under vacuum. The solidified casting was sectioned ...
There are a number of ways to rectify this situation. The first is obviously place a requirement on the drawing for maximum porosity. Another is to use a vacuum die casting process, which substantially reduces or eliminates porosity. Gibbs Die Casting in the US is one casting vendor that uses...
Porosityis defined as the percentage of void space in a solid[31]and it is a morphological property independent of the material. Pores are necessary forbone tissue formationbecause they allow migration and proliferation of osteoblasts andmesenchymal cells, as well as vascularization[32]. In addition...
Porosity in a die casting occurs when there is an air pocket that forms because air or gas is entrapped or by the metal shrinking away.
Lethiguel SAS announces complete acquisition of Midland Technologies Inc. Lyon, July the 5th: Lethiguel company, a French firm operating in the light metal casting industry, has acquired a 100% stake in Midland Technologies Incorporated, Minneapolis-based casting solution provider [...] ...
3.13.5.1 Elastic Analysis of Thermal Strains in the Presence of Porosity Residual porosity at a microscopic scale is commonly observed in MMCs. Such porosity may result from incomplete infiltration due to lack of wetting of the reinforcement by the liquid metal. Residual porosity is also very diffi...
A detailed uncertainty-analysis model is developed for metal-casting porosity measurement using Archimedes'' principle. The model is used to investigate the influence of liquid density on the sensitivity coefficients in the uncertainty propagation equation. The sensitivity coefficients are found to be ...
