Abstract

In this study modification of AA2024 microstructure produced by friction drilling was investigated. To reveal the role of deformation, high temperature and friction on microstructure modification methods of optical and scanning electron microscopy and microhardness test were used. Different zones of material around friction drilling hole has a special characterization through grain size, volume fraction and size of incoherent second phase particles and microhardness. It has been found that deformation, high temperature and friction in friction drilling process lead to recrystallization of grain structure and dissolution of incoherent second phase particles due to strain-induced dissolution effect. Microhardness of recrystallized material has increased.
