Abstract
The continuous cooling transformation diagrams of titanium-base binary alloys of eutectoidal type have been reported by the present authors in the paper No. 1 of the same title. This paper summarizes the continuous cooling transformation diagram of five titanium alloys ; Ti-Pb, Ti-Ag, Ti-Pt, Ti-Cu and Ti-Ni. These alloys also belong to the eutectoidal type.
As the results of this experiments, additional elements have been classitied into the following two district groups through the difference in effecting the upper critical cooling velocity ;
(1) elements which decreas the critical cooling velocity ; V, Cr, Mo, Nb, Pt, Co, Sn, Zr.
(2) elements which increase the critical cooling velocity ; Cu, Ag, Pb, Bi, Al, Fe, Mn, Ni.
