Constitutive modeling of the slip-twinning transition in martensitic transformations
Martensite is the result of a diffusionless displacive phase transition. In Fe-based alloys it transforms the FCC to the BCC, BCT, or HCP structures and occurs at high strain rates. It has two typical morphologies, known as lath and plate. A quantitative

ABSTRACT This work presents a fully thermomechanically coupled material model for shape memory alloys (SMAs), capable of predicting shape memory effect, superelasticity, stress and strain recovery, and martensite reorientation. Formulated within the Generalized Standard Material (GSM) framework, the model employs a rate potential, whose variations ...

Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Where Can Aluminum Go When Batteries Die?
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

Alloying Strategies for Secondary Hardening in High‐Boron Cold Work Tool Steels: A Comparative Study
The influence of tungsten, vanadium, manganese, and silicon on the microstructure and tempering behavior of high boron tool steels is investigated. It is shown that tungsten contributes very little, whereas vanadium leads to tempering carbides, detected by atom probe tomography. Manganese and silicon enable solid solution strengthening. A high hardness

Damage Behavior of Ni‐B and Ni‐B‐TiO2 Coatings on AISI P20 Steel Under Indentation and Bending
ABSTRACT This study examines the influence of TiO2 nanoparticles on the structure, mechanical properties, and fracture behavior of Ni‐B coatings applied to heat‐treated AISI P20 steel. Mechanical performance was assessed through indentation and step‐by‐step three‐point bending tests on both coated and uncoated substrates.
