Abstract
The invention belongs to the technical field of metal micro-forming, and in particular relates to a method for inflating micro-channels. The present invention is aimed at the problems of low process flexibility, single product type, and non-closed structure of the micro-channel when preparing metal micro-channels by micro-plastic forming of ultra-thin metal strips. The present invention uses a method combining numerical simulation and bond rolling experiment to analyze the effect of the hydrogen pressure and bond strength of the metal composite ultra-thin strip after bond rolling on the pore diameter of the micro-channel, and the corresponding relationship between the micro-channel pore diameter and the titanium hydride content, heating temperature, and bond strength of the metal composite ultra-thin strip is obtained.
