A process for making a clad article of a densified metal powder core and a compatible metal cladding metallurgically bonded thereto results in a significantly reduced concentration of metal oxides in the core so as to prevent embrittlement of the core at and adjacent the core/cladding interface that results in rupture between the core and the cladding along the interface during working or forming. In carrying out the process, the temperature of the undensified metal powder and/or the temperature of the compatible metal container into which the metal powder is filled are closely controlled so as to avoid adsorption of moisture during the filling step.
