Initiation of dynamic recrystallization of as-cast N08028 alloy
The use of high nickel content austenitic stainless steels (SASS) has significantly increased in the last decade. The corrosion and high fatigue resistance of these materials make them suitable for manufacturing oil country ...
Characterization of Ti64 forging friction factor using ceramic coatings and different contact conditions
Hot forging processes are highly influenced by the contact conditions between the billet and the dies. A wrong definition of the contact conditions may lead to wrong predictions of the final component geometry, the quantity ...
Contact pressure, sliding velocity and viscosity dependent friction behavior of lubricants used in tube hydroforming processes
The final quality of sheet and tube metal formed components strongly depends of the tribology and friction conditions between the tools and the material to be formed. Furthermore, it has been recently demonstrated that ...
Contact pressure and sliding velocity ranges in sheet metal forming simulations
In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ...
Roll levelling semi-analytical model for process optimization
Roll levelling is a primary manufacturing process used to remove residual stresses and imperfections of metal strips in order to make them suitable for subsequent forming operations. In the last years the importance of ...
Sensitivity analysis on an AC600 aluminum skin component
New materials are been introduced on the car body in order to reduce weight and fulfil the international CO2 emission regulations. Among them, the application of aluminum alloys is increasing for skin panels. Even if these ...
