抄録

In the previous paper on the cause of banded structure, the following results were reported; if two specimens, their chemical composition being different from each other, were welded together and then slowly cooled after austenitizing, inhomogeneous structure appeared, whereas air cooling never showed such a structure. It was also shown that these phenomena were affected by elements such as P, Ni, Cr or Mn.<BR>In the practical welding, it may be occurred that different kind of steels must be welded. In this paper, the effects of the other elements on these phenomena are reported. The results are summarized as follows:—These phenomena are effected not only by Ni, Cr, Mn or P but also by all kind of elements used in this experiment. Although a group of elements makes pearlite structure appear on the side of the specimen in which the element is added, the other one makes ferrite structure there.<BR>In the discussion of these results, two assumptions are introduced, and it was made clear that these phenomena can well be explained from the view point of physical metallurgy.
