Substitution of Ti by Nb in Maraging Steel: Effects on Strengthening Mechanisms and Crystallographic Behavior

steel research international, EarlyView.
This work demonstrates that replacing Ti with Nb in maraging steel forms nanoscale Nb–Mo particles along boundaries, strengthening the alloy without relying on Ti phases. Heat‐treatment tuning promotes uniform crystal orientation and balanced grain boundaries, enabling strong yet ductile behavior.

Correlation Between Evaporation Dynamics and Self‐Healing Characteristics in Metallised Polypropylene Films

High Voltage, EarlyView.
ABSTRACT The morphology and structure of electrodes play a pivotal role in determining the self‐healing performance and current‐carrying capacity of metallised biaxially oriented polypropylene (BOPP) films. An experimental setup replicating the industrial vacuum evaporation process and a custom‐designed self‐healing testing platform were specifically ...

Failure Probability Evaluation of GIL Tri‐Post Insulators Under Electromechanical Stresses

High Voltage, EarlyView.
ABSTRACT Based on the energy theory, this paper proposes an evaluation method for the breakdown failure probability of the tri‐post insulator in a gas‐insulated metal‐enclosed transmission line (GIL). Various internal defects, vector forces and torque forces were considered, along with the application of an AC voltage.

Crystal Plasticity Modeling of Dislocation Density Evolution in Cellular Dislocation Structures

Metals
The complex thermal cycles during the solidification process in metal additive manufacturing (AM) lead to the formation of high-density dislocation networks, organizing into submicron-scale cellular structures.

CVaR sensitivity with respect to tail thickness [PDF]

We consider the sensitivity of conditional value-at-risk (CVaR) with respect to the tail index assuming regularly varying tails and exponential and faster-than-exponential tail decay for the return distribution. We compare it to the CVaR sensitivity with

Cyclic Plastic Material Behavior of Novel Austenitic (C + N) Steel Additively Manufactured by PBF‐LB/M

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The newly introduced high manganese high strength (C + N) steel Printdur HSA was developed for the additive manufacturing process PBF‐LB/M. It consists of a fully austenitic grain structure. This study aims to evaluate the cyclic plastic material behavior of this (C + N) steel.

Contextualized Metabolic Modelling Revealed Factors Affecting Isoflavone Accumulation in Soybean Seeds

Plant, Cell &Environment, EarlyView.
ABSTRACT Isoflavones, secondary metabolites with numerous health benefits, are predominantly found in legume seeds, especially soybean; however, their contents in domesticated soybean seeds are highly variable. Wild soybeans are known for higher seed isoflavone contents than cultivars. Here we used experimental and modelling approaches on wild soybean (
