Evolution of hot stamping technology: a bibliometric review

Today's huge automotive industry requires continuous innovations. In this sense, numerous publications on new materials or developments which can provide new weight reductions or safety improvements are released every day. An important example is hot stamping, which has been gaining popularity in the last years due to its advantages for the sector. Considering the strong influence of the automotive sector in world economies, we have focused our attention on the literature concerning not only hot stamping itself but also on several other technologies which are related to the same transformation procedure, to have a complete photograph of the evolution of the technology itself. We contribute with a systematic literature review process, enriched by a bibliometric review. The use of both contributes in a neutral, reliable manner, reducing the possible bias of traditional literature reviews, which have been previously employed in this specific discipline. We have resorted to the Web of Science to execute a query related to all the possible procedures that involve hot stamping technology, which correspond with 573 English peer reviewed publications from journals indexed in this database. The results clarify that hot stamping is a key issue in metallurgy publications with significant future prospects due to its manufacturing implications.
