    Study on diffusion bonding of composite metal foams by John Cance, Afsaneh Rabiei

    Published 2025-06-01
    “…Previous success was achieved in joining CMF panels up to 2.5 cm thick through induction welding, though localized heating through induced Eddy currents could not fully permeate thicker samples. This limitation has caused a shift in focus to diffusion bonding of CMF panels thicker than 2.5 cm. …”
