temperature (a) 650, (b) 630, and (c) 615°C [28].
7.3.3 SHEAR RATE
More precisely the rheological characterization can be studied with isothermal steady-
state experiments. The steady state, as dened earlier, is a state where the viscosity
remains constant for the given value of solid fraction, shear rate, and stirring time.
Hence, the steady-state viscosity is a function of solid fraction and shear rate but not of
time [29]. Joly and Mehrabian [25] illustrated the pseudo-plastic behavior for Sn-15Pb
alloy ( ...
