Small scale tensile testing technique for measuring grain boundary strength of neutron-irradiated materials in focused ion beam systems

Research output: Contribution to conference › Poster

Abstract

Irradiation induced defects on grain boundaries (GBs) can lead to GB strength degradation and cause intergranular cracking in structural materials, affecting the safe operation and service life of nuclear reactors. Establishing the quantitative relationship between the strength and character/microchemistry for individual GB in an effort of integrating experimental measurements and multiscale simulations.
