Significant austenite decomposition during slow heating of cold-rolled medium Mn steel with a high fraction of pre-existing austenite [PDF]

In-depth analysis of phase transformations during continuous heating (2.4 °C/s) of 50 % cold-rolled Fe-6Mn-2Al-1Si-0.4C (wt.%) steel with 32 % pre-existing austenite was conducted using in-situ high-energy synchrotron X-ray diffraction and ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

Advanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

Advanced Engineering Materials, EarlyView.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

Microstructure and mechanical property regulation of hot-rolled Al-contained medium-Mn steel by double intercritical annealing

Cailiao gongcheng
Usually，the initial microstructure of hot-rolled and quenched medium-manganese experimental steel is composed of lath martensite matrix and a small amount of tiny granular austenite， also existing apparent Mn-segregation bands. Using double intercritical

Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

Advanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Enhancing mechanical properties of medium Mn steel by warm rolling based on laminated elemental segregation

Journal of Materials Research and Technology
The hot-rolled microstructure of medium Mn steel has coarse grains and severe elemental segregation, resulting in low strength and plasticity. Constructing a multiphase structure, refining the microstructure, and regulating elemental segregation enhance ...

Atomic‐Scale Study on Core–Shell Cu Precipitation in Steels: Atom Probe Tomography and Ab Initio Calculations [PDF]

In the present work, the atomic interactions among Cu, Al, and Ni elements in body‐centered cubic (BCC) ‐iron matrix, focusing on the formation mechanism of nano‐sized core–shell Cu precipitates, are investigated.
