The effects of high pressure on the isothermal transformation are studied for three high purity Fe-C alloys and commercial steels. The specimens (3mm∅×3mm) are inserted into a “girdle” type high pressure apparatus and the isothermal transformation are carried out at 29 or 38.5kbar.<BR>The results obtained were as follows:<BR>(1) The rates of isothermal transformation both in Fe-C alloys and commercial steels are retarded by pressure, and the retardation is much stronger in the latter.<BR>(2) By increasing the pressure from 29 to 38.5kbar in all alloys and steels, the incubation time increases by approximately five times.<BR>(3) The structures obtained in isothermal transformation at high temperature can be explained from the phase equilibrium diagram under high pressure which is different from that at atmospheric pressure.<BR>(4) As singular structures appeared in the transformation at low temperature and high pressure, ‘aggregate’ or “columnar bainite” structures are observed in place of the acicular bainite at atmospheric pressure. The ranges in which those structures appear are determined.<BR>(5) The shape of carbide in a commercial steel containing 1.1%C changes from spherical shape to acicular one with the increase of pressure from 29 to 38.5kbar.
