Application of Machine Learning in Heat Treatment Process Design of Carburized Steel

Materials Genome Engineering Advances, EarlyView.
To accelerate heat treatment design, we constructed a closed‐loop machine learning strategy involving multi‐source datasets and feature screening. The optimized model accurately predicts hardness and friction coefficients, successfully guiding the process optimization for two typical carburized steels with high experimental consistency.

Deformation Behavior and Microstructure Evolution of NiTiCu Shape Memory Alloy Subjected to Plastic Deformation at High Temperatures

Metals, 2017
Deformation behavior and microstructure evolution of NiTiCu shape memory alloy (SMA), which possesses martensite phase at room temperature, were investigated based on a uniaxial compression test at the temperatures of 700~1000 °C and at the strain rates ...

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

The constitution of martensite volume fraction in Fe-31wt%Ni-0.02wt%C

Journal of Materials Research and Technology, 2019
This paper analyzes the constitution of martensite volume fraction, that is, the size-distribution of martensite units in quenched-transformed austenite in the microstructure. We correlate this distribution to the martensite shape-strain relaxation.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Controlling the work hardening of martensite to increase the strength/ductility balance in quenched and partitioned steels

Materials & Design, 2017
The role of retained austenite on tensile behavior in quenched and partitioned (Q&P) steels has been studied extensively, but the deformation behavior of martensite, which comprises the majority of Q&P microstructures, has received less attention.
