Static recrystallization is a method of tailoring the microstructure and mechanical properties steels, which important for microalloyed forging steels as hot deformation process significantly affects their properties. In this paper, static behavior low-carbon Nb-V-microalloyed steel was investigated by double-pass compression tests at temperature 800–1100 °C interruption time 1–1000 s. The frac...

The inactivation of Escherichia coli by microalloyed aluminium based composite was studied. The composite is material in form of steel wire, plated by microalloyed aluminium. Its effects are based on spontaneous dissolution in contact with water, with generation of Al(III) and OH ̄ ions, and finally voluminous insoluble Al(OH)3. Bearing in mind its great efficacy in purification of water from ma...

This paper deals with the influence of steel composition (with respect to the microalloying elements) and therrnomechanical treatment on structure and mechanical behaviour of HSLA (High Strength Low Alloy) steels. Four different microalloyed steels have been TM rolled under variing conditions. The austenite structure prior to transformation could be revealed by means of a special etching techni...

High temperature deformation behavior of cast 310S stainless steel has been investigated in this study by performing tensile and compression tests at temperatures from 900 to 1200C. Rectangular ingots of which the dimensions were 350×350×100 in millimeter were cast using vacuum induction melting. Phase equilibrium was calculated using the FactSage®, thermodynamic software and database. Thermal ...

The demand of highest possible effectiveness is put on all production processes, while the highest quality is demanded from products. These requirements are particularly justifi ed in the steel industry, due to high cost of technical equipment assembly and production cost. In such conditions continuous processes are of signifi cant meaning, since they facilitate maximum utilization of productio...

This paper reports on the precipitation behaviour and microstructural evolution in ~20% cold rolled NbMoV and V single microalloyed low carbon steels during intercritical annealing. The microstructure and precipitation behaviour were studied by optical and scanning/transmission electron microscopy and microanalysis, X-ray diffraction technique and Vickers hardness testing. After intercritical a...
