The so-called package morphology has been revealed in the Al-3.5Li alloy solidified directionally during microgravity test. The s/l interface has been quenched during the experiment. The 1D observation of longitudinal section of the s/l interface of the package morphology revealed doublets. The result of 1D experiment leading to doublets formation in terrestial conditions has been compared with 1D structure obtained from the microgravity test. A mathematical description of the s/l interface of doublets has been worked out. The package morphology is treated as a result of the interplay among the waves of perturbation which can appear on the plane surface of a single crystal growing in the microgravity conditions. The physical interpretation of proposed equations is given.
