(a) Experimental Al-matrix lattice-parameter change [dots; data from Table 1; experiments were performed between 425 and 448 K by Mittemeijer et al. (1981)] as a function of vol.% of Si precipitates and the predictions on the basis of equation (4) (solid line) and equation (1) (dashed line). (b) Experimental Si-precipitate lattice-parameter change [dots; data from Table 1; experiments were performed at 425 K by van Mourik et al. (1985)] as a function of vol.% of Si precipitates and the prediction on the basis of equation (3) (dashed line). The experimental lattice-parameter values were determined with a precision of 1–2 parts in 40 000. |
