Abstract
In the early heating stage by friction of friction welding, friction stir welding, spot friction welding, surface modification, and so on, conductive heat transfer plays an important role in formation of temperature field in the system, which would have direct effects upon the successive plastic flow process. In the heat transfer process of such systems, the effective dynamic coefficients of friction μ between a rotating rod and a metal plate is regarded as one of essential key parameters. However, almost no coefficients for various important industrial materials seem to have been obtained so far. In the present study, from experiments on unsteady-state friction heating and corresponding numerical calculations, the effective dynamic coefficients of friction μ using a rotating rod with a spherical tip of high speed tool steel have been evaluated for the aluminum alloy A2024, A5052 and A6061.
