Study on the damage behaviour of titanium alloy laser-welded blank during hot gas pressure forming [PDF]

MATEC Web of Conferences
The damage behaviour of titanium alloy laser-welded seam during hot gas pressure forming was studied by experiment and simulation. The GTN damage model was used to simulate the hot gas pressure forming process of the welded blank.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Effect of oscillating laser welding parameters on energy distribution and joint forming of 5A06 thick plate aluminum alloy

Hanjie xuebao
Clockwise circular oscillation (CW) laser welding experiments are carried out on 8.0 mm thick 5A06 aluminum alloy. Considering the beam oscillating trajectory and energy superposition effect, the energy distribution model of the workpiece surface is ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Collaborative and Quantitative Prediction for Reinforcement and Penetration Depth of Weld Bead Based on Molten Pool Image and Deep Residual Network

IEEE Access, 2020
Weld quality is generally determined by reinforcement and penetration depth of weld bead in arc welding. Penetration depth reflects weld strength and reinforcement reflects weld shape. What's more, there is a strong coupling between them, therefore it is

Effect of arc current on forming and mechanical properties of AZ31B/DP980 laser-induced arc welded joint

Cailiao gongcheng, 2022
Without adding any interlayers or coatings, the lap welding experiment of AZ31B magnesium alloy and DP980 high-strength steel was performed with the laser-induced tungsten inert gas welding (TIG) arc technology. Through optimizing the process parameters,

Review on the prediction of residual stress in welded steel components [PDF]

, 2020
Residual stress after welding has negative effects on the service life of welded steel components or structures. This work reviews three most commonly used methods for predicting residual stress, namely, empirical, semi-empirical and process simulation ...

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.
