Abstract : The presence of phase transition under an applied dynamic pressure similar to the (alpha to omega) phase transition realized with a static load was established. A methodology was worked out for fixing the high-temperature phase in pure titanium using pre-freezing in liquid nitrogen and an applied dynamic pressure produced by intense shock waves. A probable mechanism for observing the formation and fixing of the (beta)-phase in titanium was proposed. The described methodology for fixation can be used when studying the high-temperature phases of other pure metals.
