title = "Healing behavior of hydrogen micro pores during cold plastic deformation",
abstract = "The healing behaviors of hydrogen micropores in an Al-Mg alloy during cold plastic deformation was observed using X-ray microtomography. Local strain distribution during deformation was determined by measuring the displacement of artificially dispersed Pb particles. Our result shows that under uniform applied compressive load, the local strain distribution in the sample is significantly inhomogeneous which induces complex healing behaviors of micropores during deformation. The shrinking behavior of micropores can be explained as a function of local compressive strain. Some micropores are re-initiated by heating in position identical to those before their annihilation during plastic working even after large strain has been applied after annihilation. There were no apparent effects of local compressive strain on annihilation and re-initiation behaviors. It can be concluded that application of 60% compressive load used in this study is not sufficient enough to heal the micropores completely.",
