Heat affected zone microstructures and their influence on toughness in two microalloyed HSLA steels
Microstructures and Charpy impact properties have been examined in two microalloyed steels following heat treatments to simulate weld heat affected zone (HAZ) structures over a range of heat input conditions, characterised by the cooling time from 800 to 500 !C (Dt8/5). The base materials were low carbon structural steel plates microalloyed with vanadium and nitrogen (V–N) and niobium (Nb), res...
متن کاملSelection of Arc Welding Parameters of Micro Alloyed Hsla Steel
Like all steel types, HSLA requires a definition and strict practical adherence to welding parameters in order to achieve the required weld quality. Different sources offer a varying array of welding parameters. Although their hierarchical importance can be disputed, their principal definition and practical adherence are prerequisites for the quality of welded joints 1,2 . The analysis of earli...
متن کاملShear and tensile plastic behavior of austenitic steel TRIP-120 compared with martensitic steel HSLA-100
Themechanical performanceofTRIP-120, a novel transformation induced plasticity steel alloy, is evaluated for different loading cases and strain rates. The performance is compared with HSLA-100, a lowalloy steel developed by the United States Navy and currently used in naval hulls. The response of these materials under uniaxial tension and shear was investigated to the point of fracture at isoth...
متن کاملDynamic Characteristics of Automotive Steel Sheets
M. Mihaliková, A. Lišková, Faculty of Metallurgy, Technical University of Košice, Slovakia The aim of this experimental research was to perform an analysis of deformation characteristics on two different types of steel: IF steel, and micro-alloyed steel were used automotive industry. For that purpose changes of properties of these materials were carried out by static 10-3 · s-1 and dynamic 103 ...
متن کاملEffects of Various Process Parameters by Tensile and Toughness Test on Weld Joint Quality of HSLA Steel during Submerged Arc Welding
The aim of the present work was to study the effect of various process parameters i.e. current, voltage, travel speed, electrode diameter, flux composition, pre heating of workpiece, electrode stick-out and edge including angle on changes in tensile strength and toughness of the weld bead geometry of HSLA Steel and to optimize the process so that minimal changes occur in the material properties...
