Breaking Extrapolation Barriers: Dual Innovations for Property and Component Design of Multi‐Component Alloy

Materials Genome Engineering Advances, EarlyView.
This study breaks extrapolation barriers in alloy design by merging symbolic regression with latent space sampling. The dual‐strategy framework enables accurate prediction of high‐hardness properties and navigates uncharted compositional spaces. The approach successfully designs novel high‐entropy alloys with hardness exceeding 863.5 HV, demonstrating ...

Microstructural damage evolution in two Ni based superalloys subjected to different mechanical loading conditions through quantitative EBSD measurements using Cross-Court software

, 2014
Ni based superalloys are adopted as base materials for critical hot gas path components of gas turbines. Knowledge of the evolution of the microstructure is very important for gas turbine producers in order for them to fully predict component behaviour ...

The Effect of Microstructure on the Very High Cycle Fatigue Behavior of Ti-6Al-4V Alloy

Metals
Crack initiation plays a major role in very high cycle fatigue (VHCF) life, and the initiation of cracks is related to slip behavior. There is a need for improvement in the understanding of the influence of Ti-6Al-4V microstructures on VHCF performance ...

Creep Mechanism Mapping of Lamellar Ti–Al Alloys With Crystal‐Plasticity Phase‐Field and Interpretable Machine Learning Framework

Materials Genome Engineering Advances, EarlyView.
Crystal‐plasticity phase‐field simulations combined with stacked machine learning map the creep microstructure relationship in lamellar Ti‐Al alloys. Interpretable learning identifies lamellar thickness, elastic strain energy, and interfacial energy as dominant factors governing the diffusion‐to‐dislocation creep transition and overall creep resistance.

Analysis of the Alloying System in Ni-Base Superalloys Based on <i>Ab Initio</i> Study of Impurity Segregation to Ni Grain Boundary

, 2011
A new approach to the design of Ni-based polycrystalline superalloys is proposed. It is based on a concept that under given structural conditions, the performance of superalloys is determined by the strength of interatomic bonding both in the bulk and at

Effect of Friction Stir Welding and Tempering on the Microstructure and Strength of a Tempformed Low-Alloy Steel

Metals
The microstructure developed in a low-alloy steel during friction stir welding and post-weld tempering was studied. The quenched steel samples were subjected to tempering at 650 °C for 1 h, followed by warm rolling to a total strain of 1.5 at the same ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Impact of AC Frequency and Slag Composition on Inclusion Entrapment in Electroslag Remelting

steel research international, EarlyView.
AC current frequency and slag composition strongly influence nonmetallic inclusion transport during electroslag remelting. A stronger secondary vortex, promoted by higher frequency and CaF6 slag, drives inclusions toward the lateral wall, reducing their presence in the ingot interior.
