Ll. Zheng et al., Revised form of Jackson-Hunt theory: application to directional solidification of MnBi/Bi eutectics, J CRYST GR, 209(1), 2000, pp. 110-121
A generalized eutectic theory, which defaults to the prior theories by Jack
son-Hunt and Trivedi et al. under their boundary conditions, has been devel
oped to consider phase relations, solidification temperature and interface
velocity over the entire parametric range, and for both lamellar and rod eu
tectic morphologies. The analytical solution reveals that lambda(2)V and la
mbda Delta T, though varying with the Peclet number, are virtually constant
at very low Peclet number (crystal growth conditions). These constant valu
es, however, map vary with the phase reaction and the degree of undercoolin
