Ultra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملULTRA FINE FERRITE FORMATION IN Si-Mn TRIP STEELS
Abstract: In the present investigation, the effects of thermomechanical processing parameters and the steel chemical composition on the ultra fine ferrite formation characteristics were studied. This was programmed relying on the capabilities of strain induced transformation (SIT) phenomenon and applying to different grades of Si-Mn TRIP (Transformation Induced Plasticity) steels. According...

متن کاملCollaborative Research Project on Ultra-Low-Power Data-Driven Networking System
Power consumption will be one of the most crucial issues to realize both future VLSI chips and communication environments. This research project proposed in this paper is aiming at developing a data-driven networking system by which the coming networking environment can be achieved with ultralow-power consumption 1/100 to 1/1000 of the present. To realize the objectives, this project is plannin...
متن کاملThe Effect to Epsilon Phase on the Friction and Wear of Nitrided Die Steels (RESEARCH NOTE)
In this paper, the wear resistance and antifriction of epsilon phase layer and diffusion layer of gas nitrided D2 steel and M2 steel have been studied. The changes m wear mechanism of epsilon phase under the load from 20N to 200N are analysed. When the load is lighter than 100N, it is mainly oxidizing wear on friction surface. The adhesion, peeling off and abrasive wear appear on friction surfa...
