Towards directly formable thin gauge AZ31 Mg alloy sheet production by melt conditioned twin roll casting

Materials & Design, 2019
A novel melt conditioned twin roll casting (MCTRC) strategy with emphasis on solidification control has been investigated for producing thin gauge Mg alloy sheets ready for component forming, with the minimal requirement of down-stream processing.

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.

Single-track investigation of rapid solidification conditions of Hastelloy-X Ni-based superalloy in laser powder-bed fusion and applicability of columnar equiaxed transition criteria

Virtual and Physical Prototyping
To understand the applicability of the columnar-equiaxed transition (CET) criteria to the rapid cooling conditions unique to the powder-bed fusion (PBF) type additive manufacturing (AM) process, we investigated relationships between the microstructure ...

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
