Quantifying the dependency of uniform corrosion of structural steel on grain size
The dependency of uniform corrosion of structural steel on the average grain size (D) should be quantified for design purposes. In the present work, a spectrum of grain sizes was obtained by simple heat treatment routes in st37 structural steel. It was revealed that the corrosion current density (icorr) increased by grain refinement, which was related to the increased density of grain boundarie...
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...
متن کاملFatigue Assessment of Complex Welded Steel Structures
To improve the usage of material in fatigue loaded complex welded structures a better calculation method (based on FEA) is needed than what is available on the market and an improved management of weld quality. Improved FE-procedures are directly applicable to design of generic structural components within virtually all industries using CAD and FEtools, irrespective of industrial sector. More a...
متن کاملCold End Forming Of Welded Steel Tubes
The production of custom and specific tube end shapes by cold end forming using a die is generally limited to seamless tubular parts. Current research work in the field follows the same trend as that of industry and, therefore, there is no accumulated experience, no practical design rules, and no information available in the specialized literature concerning the utilization of tube end forming ...
