Overview: Machine Learning for Segmentation and Classification of Complex Steel Microstructures

Metals
The foundation of materials science and engineering is the establishment of process–microstructure–property links, which in turn form the basis for materials and process development and optimization.

Failure analysis of a hydraulic press clamp

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
This paper describes the analysis and investigation of the causes of the failure of an hydraulic press jaw face grip. Analysis of the fractured surfaces indicated the creation of cracks due to stress concentrators as a result of defective design. On the

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Experimental Determination of a Strain State in a Bulk Forming of a Low Carbon Steel

Medžiagotyra
An experimental metallographic method for determining strain distribution in a cold formed workpiece is presented in this paper. The method, based on the dependence of recrystallized grain size on prior deformation, was applied to a bulk formed element ...

Atomic Scale Insight Into High Voltage Degradation Mechanism in YSZ Electrolyte for Solid Oxide Electrolyzer Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The evolution of yttria‐stabilized zirconia (YSZ) electrolyte microstructure after testing at progressively high voltages was captured at the micro‐ and atomic‐scale levels to determine the operational boundaries of a solid oxide electrolysis cell (SOEC).

Effect of Heat Treatment Parameters on Microstructure, Hardness, and Corrosion Resistance of Martensitic Stainless Steel X30Cr13 (AISI 420B)

Materials and Corrosion, EarlyView.
The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these
