Mechanical and microstructural properties of duplex steel

In this work mechanical properties and microstructure of duplex steel after heat treatment are shown. Heat treatment of the steel consisted of water quenching from 1050oC. A ferrite-austenite microstructure was obtained and the brittle sigma phase was avoided. The results show that the impact energy depends on the direction of rolling. In rolling direction the share of ferrie and austenite was approximately equal.
