Abstract
It is not yet determined whether in the mechanical mixture of powder of metals which form a eutectiferous alloy by melting the eutectic reaction takes place on heating course at the normal eutectic temperature or not Therefore the present authors have attempted to make this problem clear.
By using compressly formed specimens made of the mixture of powdery metals of simple binary eutectiferous system,the thermal changes of it was measured by the differential thermal analysis. And it is observed that such a mixture begins to melt at the eutectic temperature just like as the case of eutectic alloy made by melting.
The thermal behaviour at the contacted surface of two metal blocks which form a eutectiferous alloy by melting have also been studied. When they are heated at higher temperature than the eutectic point,the both metals melt at the contacted surface and form a layer of eutectic alloy.
From these experiments,the present authors have introduced some discussions on the interfacial reaction of contacted metals.
