Abstract Scope |
The researchers are looking for combination of both cost-benefit and optimal content of Scandium to achieve effective strengthening for the replacement of 5083 alloy, which is widely used in marine construction. 5181 alloy contains 0.03%Sc and designed for marine and transportation industry. In order to achieve advanced strength some substitution of Sc was added. Complex alloying with transition metals require fine-tune of thermomechanical processing parameters. Marine construction also use various extrusions and Sc together with other additives may result in different negative effects on it like press-effect. The aim of the present study is to determine the optimal extrusion parameters and heat treatment of 5181 alloy extrusion, which ensures the achievement of a 20% improved strength compared to the profile made of 5083 alloy. The influence of the extrusion speed, heating temperature of billets and modes of heat treatment on the mechanical properties of extruded semi-finished products was studied. |
