NIMS has long worked on developing advanced steel techniques, namely, producing advanced steels by using only simple alloying elements such as carbon, manganese, and silicon, and also by utilizing steel scrap. The hope is that this approach will lead to a technology of a so-called steel-to-steel recycling process, with the ultimate goal of a recycling process such as an automotive-steel-to-automotive-steel recycling process to take the place of the current cascade-type recycling system. The main idea is to utilize ultra-grain refining structures and hetero structures as well as martensite structures. In particular, the focus of this book is on tensile strength and toughness of advanced steels from both the fundamental and engineering points of view. Fundamentally, a unique approach to analysis is taken, based on fracture surface energy as effective grain size is employed to better understand the mechanism of property improvement. From the engineering point of view, in fracture toughness such factors as crack tip opening displacement (CTOD) of advanced steels are evaluated in comparison with those of conventional steels. 410 0$aNIMS Monographs,$x2197-8891 606 $aMetals 606 $aManufactures 606 $aStructural materials 606 $aMaterials science 606 $aMetallic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z16000 606 $aManufacturing, Machines, Tools, Processes$3https://scigraph.springernature.com/ontologies/product-market-codes/T22050 606 $aStructural Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z11000 606 $aCharacterization and Evaluation of Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z17000 615 0$aMetals. 615 0$aManufactures. 615 0$aStructural materials. 615 0$aMaterials science. 615 14$aMetallic Materials. 615 24$aManufacturing, Machines, Tools, Processes. 615 24$aStructural Materials. 615 24$aCharacterization and Evaluation of Materials. 676 $a669.96142 700 $aHanamura$b Toshihiro$4aut$4http://id.loc.gov/vocabulary/relators/aut$01065310 702 $aQiu$b Hai$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910298660403321 996 $aAnalysis of Fracture Toughness Mechanism in Ultra-fine-grained Steels$92544454 997 $aUNINA
