■ Abstract : Delayed Fracture and Its Evaluation Method
The speaker, FN, worked for Sumitomo Metal Industries, Co.Ltd (SMI) for almost 43 years (April, 1975~August, 2012). His duty covered R&D on long products, materials testing and evaluation, customer service to major Japanese automobile companies, and education of young engineers of SMI, its subsidiary companies, and its customers. Among many R&D areas he got involved in, delayed fracture has
been his life-long subject. This fracture is closely related to the performance of high -strength steel products used in various environments in the market. Typical delayed fracture is a hydrogen-induced in-service failure is of high strength bolts.
FN describes his R&D work to fight against this fracture. He also introduce a new
criteria of delayed fracture susceptibility applicable to an actual high strength structural components. Throughout his speech, FN will outline how he got involved in these R&D subjects, his successes and failures, the desirable R&D engineer's mindset, etc. He will also refer to the future outlook on the above subjects.
