F. Vermolen et al., THE DISSOLUTION OF A STOICHIOMETRIC 2ND-PHASE IN TERNARY ALLOYS - A NUMERICAL-ANALYSIS, Materials science & engineering. A, Structural materials: properties, microstructure and processing, 246(1-2), 1998, pp. 93-103
A general numerical model is described for the dissolution kinetics of
stoichiometric second phases for one-dimensional cases in ternary sys
tems. The model is applicable to both infinite and finite media and ha
ndles both complete and incomplete dissolution. It is shown that the d
issolution kinetics of stoichiometric multicomponent second phase part
icles can differ strongly from that of the mono-element particles. The
influence of the soft-impingement, ratio of the diffusion coefficient
s, stoichiometry, composition and the geometry of the dissolving stoic
hiometric phase is shown. The model is applied to an AlMgSi-alloy. (C)
