オーステナイト時効(オーステンパリング)中の異相變化に就いて

The heterogeneous reaction occurring in the course of austempering has been explained by the heat treatment diagram. The heat treatment diagram is a sort of double diagram, -a common diagram added. with a metastable one. Wether does occur during austempering any other stabilization change than the heterogeneous reaction?-it is a future problem to research.
