Abstract
A method of and apparatus for sinter forging a precursor powder to form a film may reduce or eliminate the stress in the film and may facilitate processing of continuous length of films such as ceramic films for use in batteries. The precursor powder can be provided on a substrate and is simultaneously heated and pressed in a pressing direction parallel to a thickness of the film so as to sinter and densify the precursor powder to form the film in a sinter forging area. Notably, in a plane perpendicular to the pressing direction, there are no lateral constraints on the sinter forging area or the material received therein.
