Many results were reported on the martensite transformation Al-bronze, but the theories on the mechanism of this transformation are not yet satisfactorily established. For this reason, to treat the problem of this momentary transformation in a fundamental manner, the writers have considered the factors that govern this transformation. In the present work, phenomena and mechanism of its transformation were re-examined not only by means X-ray analysis, photomicrostructure and specific gravity methods but also by an instantaneous measuring apparatus consisting of a set of magnetic ocillograph and amplifier devised newly. From the results obtained, it was ascertained that martensite transformation of this alloys is necessarily followed by a shear mechanism to some extent and that the process of martensite formation progresses in certain colony at a velocity of 10-2~10-3 second.
