A Study on Fatigue Characteristics of Dissimilar Spring Steel(SUP9A)-SM25C by Friction Welding
스프링강(SUP9A)-SM25C의 이종재 마찰용접 피로특성에 관한 연구
Abstract
The friction-welding SM25C is a substitute for the suing steel that is utilized in the machinery, airplane, and automobile, ok. This substitution would provide reduction of material and weight of welding parts. From the result we found that the strength of the friction welded joint was 529-617MPa and the toughness 1.2 times higher than that of the base metal. The optimal condition of friction welding was found as follows : n=2000rpm,
