摘要：

We discover that a weak uniaxial stress of the order of 10(-3) bar leads to a dramatic change of the Mullins-Sekerka instability. The threshold together with the microstructure scale are shifted by amounts going up to one (or several) decade(s). This effect should open new lines of both experimental and theoretical inquiries.
