Technical Intelligence Approach: Determining Patent Trends in Open Die Forging

Abstract

Open die forging is an important process for alloys and steels present in a variety of industries, such as in the aerospace industry, construction, mining and general machinery. During the forging process several wear mechanisms occur: thermal fatigue, plastic deformation, mechanical fatigue, etc. causing quality damage and economic losses. Academy and industry are devoting significant efforts to confront this situation where research acquires a key role. Under this context the objective of our research is to apply patent analyses as part of a Competitive Technical Intelligence methodology on open die forging. In particular, a keyword-based patent analysis and a patent citation analysis were develop
