Analytical modeling of work hardening of duplex steel alloys in the milling process

چکیده
Severe plastic deformation in cutting operations such as milling might change mechanical properties (especially the strength and hardness) of machined surface its underlying layers. This phenomenon called work hardening reduces machinability. study presents an analytical solution to calculate upper layers workpiece process 2205 duplex stainless steel. In this regard, stresses regions are calculated find stress temperature fields workpiece. Then strain rate values for each point subsurface using determined field. Finally, Johnson-Cook material model is used flow hardening. Experimental results different machining conditions have been validate proposed model. However, comparisons microhardness resultant force obtained by with experimental tests showed that properly predicts amount
