Conclusions
-
1.
In superrapid hardening in the layer remelted in laser irradiation of originally nonhomogeneous Fe83B17 alloy three areas are formed, inclusions of α-iron crystals, an amorphous zone, and an intermediate boron-enriched layer.
-
2.
Crystallization of the amorphous areas obtained in laser treatment occurs in more than one stage in a broad temperature range. With an increase in the number of laser irradiations the thermal stability of the amorphous areas decreases.
