Optimization of austenitic and ferritic steels for deep drawing. Part 2: FEM analyses with damage development.

Andrea Casaroli, Edoardo Scabini, Marco Virginio Boniardi, Riccardo Andreotti, Barbara Rivolta

Deep drawing of sheet metal is a crucial industrial process due to its high productivity and low cost per unit produced. Stainless steels are ideal for this process, given their high deformability compared to other steels. Despite its…

15-15Ti(Si) austenitic steel: creep behaviour in hostile environment

Alessandra Strafella, Antonino Coglitore, Paride Fabbri, Elena Salernitano

This work aims at studying the creep behaviour of 15-15Ti(Si) austenitic steel, under uniaxial stress (range of 300-560 MPa), and its interaction with liquid lead. The steel was tested to verify its sensitivity to Liquid Metal…
