Weldability Investigation of Fine-grained S1100ql Steel
I. Samardžić, Faculty of Mechanical Engineering Slavonski Brod, Croatia, A. Ćorić, Bratstvo, Novi Travnik, Bosnia and Herzegovina, M. Dunđer, Department for Polytechnic, University of Rijeka, Croatia. This paper presents the results of weldability investigation on welded joints made of fine grained high-strength S1100QL steel. The investigations are performed on two welded plates by HV 10 hardn...
متن کاملModeling of acetylene pyrolysis under steel vacuum carburizing conditions in a tubular flow reactor.
In the present work, the pyrolysis of acetylene was studied under steel vacuum carburizing conditions in a tubular flow reactor. The pyrolysis temperature ranged from 650 degrees C to 1050 degrees C. The partial pressure of acetylene in the feed mixture was 10 and 20 mbar, respectively, while the rest of the mixture consisted of nitrogen. The total pressure of the mixture was 1.6 bar. A kinetic...
متن کاملA Fine Grain, High Mn Steel with Excellent Cryogenic Temperature Properties and Corresponding Constitutive Behaviour
A Fe-34.5 wt % Mn-0.04 wt % C ultra-high Mn steel with a fully recrystallised fine-grained structure was produced by cold rolling and subsequent annealing. The steel exhibited excellent cryogenic temperature properties with enhanced work hardening rate, high tensile strength, and high uniform elongation. In order to capture the unique mechanical behaviour, a constitutive model within finite str...
متن کاملUltra-fine Grained Bulk Steel Produced by Accumulative Roll-bonding (arb) Process
Much attention has been directed recently to ultra-grain refining of metallic materials, where the grain size is reduced to less than 1 mm. It is expected that submicrometer grained structure would result in high strength and toughness at ambient temperature [1] as well as high strain rate or low temperature superplasticity at elevated temperatures [2,3]. It has been reported recently that ultr...
متن کاملPossibility of Determining Steel Grain Size Using Ultrasonic Waves
The microstructure of steel is decisive for its chemical, physical and mechanical properties. Depending on the parameters characterising liquid metal as well as the parameters of the steel casting influencing the crystallisation process, the macrostructure of casts and ingots consist of three, two or only one crystallisation zone. In steel ingots, its most frequent by consist of three zones: ch...
