Investigation of structural changes in resistance spot welding of advanced high strength steel DP590
The structural and hardness developed in advanced high-strength steel DP590 have been investigated with the help of optical microscopy and scanning electron microscopy on resistance spot welded specimens. The hardness diagram of the weld sections was prepared by microhardness test and the temperature peak and heat distribution were simulated by menas of the Abaqus software. The results show tha...

متن کاملMicrostructure characterisation of a high strength steel weld metal containing the novel constituent coalesced bainite
An experimental high strength steel weld metal containing 7 wt. % nickel and 2 wt. % manganese was found to have a complex microstructure. Employing high resolution characterisation techniques the microstructure consisted primarily of a mixture of martensite, upper bainite and a novel constituent with large grain size that contained plate-like precipitates. This constituent was characterised to...
متن کاملDuctile Failure in High Strength Steel Sheets
Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usag...
متن کاملNew Developments with C–Mn–Ni High Strength Steel Weld Metals — Part A. Microstructure
The relationship between alloying content, microstructure and properties has been studied for high strength steel weld metals with 7 to 9 wt. % nickel. Neural network modelling suggested that manganese reductions lead to large impact toughness increases and that nickel must be added in a controlled manner with respect to manganese in order toincrease impact toughness. Carbon additions were pred...
