We present a simplified model which reproduces the evolution through avalanches found in athermal martensitic transformations. The model is based on the Random Bond Ising model driven with an external field which mimics the effect of either the external stress or temperature. We have obtained power law distributions for the avalanche sizes in qualitative agreement with very recent experiments on martensitic transformations in Cu based alloys.
