Effect of Initial Microstructure on Impact Toughness of 1200 MPa-Class High Strength Steel with Ultrafine Elongated Grain Structure
TL;DR: In this article, a medium-carbon low-alloy steel was prepared with initial structures of either martensite or bainite, and warm caliber-rolling was conducted at 773 K (500 K) to obtain ultrafine elongated grain (UFEG) structures with strong 〈110〉/rolling direction (RD) fiber deformation textures.
Journal ArticleDOI
Notch shape dependence of fatigue crack extension in equiatomic CrMnFeCoNi high-entropy alloy
Kai Suzuki,Shigeru Hamada,Motomichi Koyama,Motomichi Koyama,Kaneaki Tsuzaki,Kaneaki Tsuzaki,Kaneaki Tsuzaki,Hiroshi Noguchi +7 more
TL;DR: In this article, the authors conducted fatigue tests on an equiatomic CrMnFeCoNi high-entropy alloy with three different micro-stress concentration sources and found that the fatigue crack extension mode was transited by the severity of the strain concentration from the damage accumulation mode to the plastic deformation mode.
Journal ArticleDOI
Substructure and crystallography of lath martensite in as-quenched interstitial-free steel and low-carbon steel
Akinobu Shibata,Goro Miyamoto,Shigekazu Morito,Akiko M. Nakamura,T. Moronaga,Houichi Kitano,Ivan Gutierrez-Urrutia,Toru Hara,Kaneaki Tsuzaki +8 more
TL;DR: In this paper , the substructures and crystallographic features of as-quenched lath martensite in interstitial-free (IF) steel and low-carbon steel (0.2C steel) were investigated using focused ion beam-scanning electron microscopy serial sectioning and advanced transmission electron microscope.

High toughness steel and a method for manufacturing the same
TL;DR: In this paper, a steel in a state of austenite is subject to deformation in not less than 30% of the total area reduction rate at a temperature region which is lower than recrystallization temperature of Austenite.
Journal ArticleDOI
Determination of α/γ phase boundaries in the Fe–Cr–Ni–Mn quaternary system with a diffusion-multiple method
TL;DR: The phase boundary between the ferrite phase (α) and the austenite phase (γ) were investigated in the iron-rich corner of the Fe-Cr-Mn-Ni quaternary system at 1000°C using a diffusion-multiple technique.
