摘要：
The purpose of this paper is to study the compression behavior of a duplex stainless steel after several annealing conditions, in order to simulate the response during cold rolling in the industrial process. For each studied condition, stress-strain curves present serrations in the flow zone due to austenite and ferrite twinning and the austenite phase transformation to martensite. At the same time, it is shown that sigma phase increases the strength and diminish the cold deformation capacity of the steel.
