On the Peritectic Reaction (1st Report). Relationship between the Process of the Peritectic Reaction and the Relative Position of the Three Phases on the Peritectic Line

Tomonori Sakano


Abstract:

Regarding the peritectic reaction, few fundamental researches, especially microscopic and systematic investigations are found. We cannot say that the perfect process always takes place on the peritectic reaction (L(Liquid)+P(Solid)S(Solid)), for it is the heterogenous reaction which occurs between the liquid and the solid. In fact, it frequently shows in the binary or ternary peritectics that the grain-refined structure results as its ideal process and the so-called peritectic structure in which the primary is enveloped by the secondary, results as its imperfect process. The author's object in this article is therefore to examine these different appearances, and to understand metallurgically the reason for this phenomena from the diagramtical point of view. This report regards the relationship between the process of the peritectic reaction and the relative position of the three phases on the peritectic line, on the occasion of the LS/SP type's binary system.
