Metal Chasing Vanishing Foam

Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode! Episode 124 of the Professor Alex Volinsky podcast. In lost foam casting, a polystyrene pattern vaporizes as molten metal advances to take its place — near-net-shape parts with no parting lines, but filling is the critical step. The metal front couples fluid flow with heat transfer and foam decomposition; trapped vapors mean cold shuts and gas porosity. Based on the paper: Simulations and Experiments of Mold Filling in Lost Foam Casting; F.J. Li, H. Zhao, F.Z. Ren, S.B. Song, X.H. Shao, A.A. Volinsky; International Journal of Cast Metals Research, 2020, Vol. 33(4-5), pp. 194-200. Hosts Elena and Marcus. AI-generated voices.
