Hydroforming of locally heat treated tubes [PDF]
Journal of Manufacturing Processes, 2014 Abstract In tube hydroforming, the process chain can be very long as it may involve several pre-forming operations (e.g. bending, crushing, end forming, etc.) which are usually followed by an intermediate annealing stage. Conventional annealing is performed in batches and it is often perceived as a long, relatively expensive and non-environmentally ...
