Effect of retained austenite on the fracture behavior of a novel press-hardened steel

Zhisong Chai et al.

Summary: This study systematically investigates the effect of retained austenite (RA) on the tensile and bending properties of a newly developed Cr and Si alloyed press hardened steel (PHS). Mechanically stable RA provides the optimal combination of tensile and bending performance, while RA with poor mechanical stability leads to a reduction in bending toughness. These findings provide useful insights for optimizing the hot stamping process of the Cr and Si-containing PHS.

The influence of in-situ alloying of electro-spark deposited coatings on the multiscale morphological and mechanical properties of laser welded Al-Si coated 22MnB5

M. Shehryar Khan et al.

Summary: This study shows that modifying the Al-Si coating prior to laser welding using electro-spark deposition (ESD) can prevent the formation of alpha-ferrite in the fusion zone (FZ). By adding alloying agents, the FZ can be simultaneously dispersed and solid-solution strengthened, leading to significantly improved mechanical properties of the welded joint. This work is highly relevant to the production of novel materials with highly optimized properties.

The effect of laser impingement angle on the optimization of melt pool geometry to improve process stability during high-speed laser welding of thin-gauge automotive steels

M. Shehryar Khan et al.

Summary: This study explores the optimization of high-speed laser welding of thin-gauge automotive steels by changing the laser impingement angle during open-keyhole mode welding. The findings show that by optimizing the laser impingement angle, the melt pool geometry can be effectively controlled, eliminating surface defects in the welds. These findings are of major relevance to industries using fiber laser systems in welding and additive manufacturing applications.

Laser-assisted wire cladding using a retrofitted laser welding system

M. Shehryar Khan et al.

Summary: This study retrofitted a traditional Ytterbium-doped fiber laser welder with a MIG welder wire-feeding system to obtain laser cladded surfaces without specialized equipment. Observations were made using a high dynamic range camera to understand material deposition modes, and process-related mechanisms were proposed to explain these modes. By carefully selecting process parameters, defect-free depositions with good surface finish can be achieved.

Carbon redistribution in quenched and tempered lath martensite

L. Morsdorf et al.

Summary: This study investigates the tempering-induced carbon redistribution in martensitic steels, revealing the formation and dissolution of carbon clusters in the as-quenched state, and the simultaneous precipitation of carbides at carbon-rich dislocation cores during tempering. The dislocation network plays a crucial role as a carbon diffusion path in the process.

Characteristics and mechanisms of hydrogen-induced quasi-cleavage fracture of lath martensitic steel

L. Cho et al.

Summary: This study provides a detailed characterization of the microstructures and dislocation characteristics beneath hydrogen-induced quasi-cleavage fracture features of an as-quenched martensitic steel. The dominant fracture mode in the hydrogen-affected zones was found to be quasi-cleavage fracture, involving significant plasticity. The sizes, orientations, and boundaries of the martensite constituents influenced the surface morphologies of the quasi-cleavage fractures.

Engineering mechanical properties by controlling the microstructure of an Fe-Ni-Mn martensitic steel through pre-cold rolling and subsequent heat treatment

Hamidreza Koohdar et al.

Summary: Experiments revealed that prior cold rolling influences the microstructure and mechanical properties of the Fe-10Ni-7Mn martensitic steel, leading to the formation of reversed austenite and transformation of martensite during post-deformation intercritical annealing. Additionally, precipitation of NiMn particles after subsequent ageing increases the ultimate tensile strength.

On the austenite stability of cryogenic Ni steels: microstructural effects: a review

W. X. Zhang et al.

Summary: Austenite stability is crucial for improving the cryogenic toughness of cryogenic Ni steels, with factors such as enrichment of austenite-stabilizing elements, grain refinement, and volume fraction of austenite playing key roles. Mechanical stability is also influenced by factors such as grain orientation and dislocation multiplication, impacting the effectiveness of enhancing cryogenic toughness.

Optimizing weld morphology and mechanical properties of laser welded Al-Si coated 22MnB5 by surface application of colloidal graphite

M. Shehryar Khan et al.

Summary: Tailor-welded blanks made of press-hardened steels are used to produce highly optimized parts for vehicle body-in-white applications. The presence of Al-Si coating in these steels during laser welding promotes the formation of ferrite in the fusion zone, leading to premature failure, which is currently resolved by laser ablation of the coating. Welding Al-Si coated 22MnB5 steel through a colloidal graphite coating eliminates the need for a separate ablation step, resulting in improved mechanical properties of the weld.

Summary: The study demonstrated that adding nickel to the fusion zone of laser-welded Al-Si coated 22MnB5 steel can suppress ferrite formation, improve weld strength, and successfully shift failure from the fusion zone to the base material, eliminating the need to remove the Al-Si coating prior to welding.
