Abstract

The behaviour of the highly reactive interfaces during the processing of nanocrystallised multilayered materials
has been investigated in the present work. Conditions leading to the formation of strain localisations around the
oxidised interfaces during the thermomechanical stage of the duplex processing route have been investigated
using multilevel numerical analysis. The analysis is based on the finite element methodology and involved
coupling of the macro level model representing the rolling of the multilayered metallic material at elevated
temperatures with the meso level model representing the oxidised interface within the nanocrystallised
material. The multilevel thermomechanical model has been applied for the analysis of the strain, stress and
damage evolution around the oxidised interfaces for the different technological parameters. The analysis
included verification of the modelling results with the available experimental material. The 316L stainless steel
is considered in the investigation.
