WebJan 1, 2001 · From a theologi- cal standpoint, the Rheocast metal is, there- fore, a fluid "slurry" and one can ascribe a viscosity to this fluid. Results of typical vis- cosity measurements are shown in Fig. 2 for several different shear rates, ~0. Look first at the curve for any one shear rate, such as ~ = 350 s-1. WebSep 19, 2024 · Thixocasting requires special pretreatments of the 27 billets to be reheated and struggles with material and process cost for aluminium. Rheocasting does 28 not have the same difficulties with process cost, not materials costs as standard alloys can be used 29 and are now expanding strongly for aluminium [3].
