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...

Strain induced precipitation in HSLA-100 steel was investigated by conducting hotcompression and relaxation tests at temperature range of 850°C to 1100°C and strain rate of 0.001s-1 to 1s-1. The absence of dynamic recrystallization at temperatures below 1000°C was attributedto the influence of dynamic precipitation. The stress relaxation tests showed that strain inducedprecipitation is possible...

The effect of copper (Cu) on hot-rolled 301 austenitic stainless steel (ASS) was studied by observing the microstructures and testing electrochemical corrosion resistance properties. results showed that, with increase in Cu content, size shear zones ASS decreased, number increased, which increased uniformity microstructure macroscopically. presence decreased stacking fault energy at elevated te...

Additive manufacturing with steel offers new opportunities for the construction sector. In particular, direct energy deposition (DED) processes such as Wire Arc Manufacturing (WAAM or DED-Arc), are able to create large structures a high degree of geometric freedom, like force-flow-optimized nodes and frameworks, well truss structures. By using high-strength steel, times can be shortened because...

Modern vehicle bodies make intensive use of high strength steel grades to meet the contradicting demand of lighter weight and simultaneously better mechanical performance. For many steel grades microalloying by niobium is the key to achieve their characteristic property profile. In HSLA steels niobium enhances the strength primarily by grain refinement. In interstitial free high strength steels...

this paper investigates the residual stress fields in the vicinity of weld bead in hsla-65 steel weldments using a neural network. this study consists of two cases: (i) the experimental analysis was carried out the measurements of residual stresses by xrd technique. many different specimens that were subjected to different conditions were studied. the values and distributions of residual stress...
