摘要：

The structure of a hot-rolled plate from duplex stainless steel 2205 is studied after solution treatment. The morphology and the content of phases in the structure of the steel are analyzed after various treatments. The mechanical properties of the hot-rolled plate are determined after austenitization at 1050 & DEG;C, when the ferrite-to-austenite proportion in the structure is 1-to-1. The heat treatment providing removal of & sigma;-phase from the structure is determined. A phenomenological model of two-stage evolution of the morphology of the austenite is suggested. A heat treatment yielding high mechanical properties meeting the ASTM standards in the hot-rolled plate is recommended.
