abstract = {The peritectic reaction consists in the growth of the
peritectic solid phase along the metastable interface
between the primary solid phase and the liquid phase. We
study theoretically the two-dimensional isothermal
peritectic reaction in the limit of small undercoolings
using the boundary-integral technique. First, we focus on
the case where the liquid phase occupies a semi-infinite
space and the peritectic phase presents a finger-like shape.
Secondly, we investigate the case where the growth takes
place in a channel of liquid phase and the peritectic phase
fills the whole channel as a product of the transformation.
It is found that for a critical channel width, the
velocities of the channel filling and the finger-like
solutions are equal. For smaller (larger) widths, the
channel filling (finger-like) solution has a larger velocity
and is likely to be predominant. This confirms some
previously reported qualitative results of time-dependent
phase-field calculations (Boussinot et al., 2010) [5]. We
also discuss the relevance of our study to directional
solidification experiments.},
