Material constitutive behaviour and microstructure study on aluminium alloys for friction stir welding [PDF]

, 2010
The material constitutive behaviour and microstructure of Aluminium alloys 6082 and 7449 were studied with the Gleeble hot compression test. The novel aspect of the work is that the testing was done at high strain-rates and at temperatures within 5 K ...

Laser Beam and Laser-Arc Hybrid Welding of Aluminium Alloys

Metals, 2021
Aluminium alloys are widely used in many industries due to their high strength-to-weight ratios and resistance to corrosion. Due to their specific thermophysical properties and intricate physical metallurgy, these alloys are challenging to weld.

Influence of corrosion and creep on intergranular fatigue crack path in 2XXX aluminium alloys [PDF]

, 2010
In this paper, two examples of the influence of time-dependent processes on crack path in two 2XXX aluminium alloys are presented. The first example is concerned with corrosion–fatigue crack growth resistance of a 2024 T351 alloy cracked in the S–L ...

Influence of tool steel alloying elements Mo and Ni on the formation of the interaction layer between tool steels and molten aluminium alloys [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
The alloying elements present in both tool steel and aluminium are influenced in the dissolution of tool steels in molten aluminum alloys. This study aims to predict how the alloying elements in the tool steel, particularly nickel (Ni) and molybdenum (Mo)

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
