| Recent investigations have demonstrated that ultra-fine grained (UFG) Al 5xxx alloys have a significant potential for industrial applications due to their enhanced mechanical and functional properties. The Al 5xxx alloys often have to undergo hot/cold rolling metalforming operations for fabrication of near-net shape products since they are widely used in form of sheets in marine, transport, and chemical engineering. The development of hot/cold rolling routes for the UFG metallic materials are very expensive due to much higher cost of the UFG metallic materials and time consuming due to numerous experimental trials. The objective of this work is to perform physical simulation of cold rolling of the UFG Al 5083 alloy obtained via equal channel angular pressing with parallel channels and to analyze the effect of cold rolling on the microstucture and microhardness of the material. It is demonstrated that physical simulation of metalforming processes for the UFG metallic materials can significantly reduce the amount of material required for development of processing routes and increase the efficiency of experimental work. |
