Critical Aspects of Alloying of Sintered Steels with Manganese

, 2010
This study examines the sintering behavior and properties of Fe-0.8Mn-0.5C manganese powder metallurgy steels. The study focuses on the influence of mode of alloying-admixing using either high-purity electrolytic manganese or medium carbon ferromanganese

Developing a Functional Polyelectrolyte Hybrid Layer Scaffold Coating and Evaluation of Its Performance for Interaction With Neural Cells

Advanced Materials Interfaces, EarlyView.
Polyelectrolyte scaffold coatings modified with Cu and Fe3O4 nanoparticles regulate neural stem cell behavior in vitro. Increased Fe3O4 content enhances mitochondrial activity and neuronal differentiation, whereas higher Cu levels reduce cell viability.

The transformation behaviour of medium manganese rail steels and its influence on their welding characteristics.

, 2018
Isothermal and continuous cooling transformation diagrams have been produced for six medium-manganese rail steels. In the isothermal experiments, specimens were heated for 15 minutes at 850°C and the progress of transformation followed by ...

Influence of Shot-Peening Treatment on Wear Resistance of Medium Manganese Steel

Journal of Materials Research and Technology
The effect of shot peening treatment on dry sliding wear behavior of medium manganese steel in as-hot rolled and solution-aging states were studied. The results show that before shot peening, the wear resistance of the solution-aging sample was better than that of hot-rolled steel.

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability

Advanced Materials Technologies, EarlyView.
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

In Situ Photopolymerization of Smectic B Liquid‐Crystalline Electrolytes from Mesogenic Phosphate–Diacrylate/Ionic Liquid Complexes for High‐Performance Soft Ionic Actuators

Advanced Robotics Research, EarlyView.
A flexible liquid‐crystalline electrolyte membrane via in situ photopolymerization of a phosphate‐functionalized mesogen, ionic liquid, and diacrylate monomer is developed. The resulting smectic B (SmB)‐phase structure enables 2D ion transport with high conductivity (10−4 S cm−1).

Phosphorus embrittlement in austenite during heat treatment of a medium-manganese steel

European Journal of Materials
Heat treatment experiments of an air-hardening medium-manganese steel show that an increase in the austenitising temperature, despite increasing the grain size, leads to better toughness values after quenching.

Plastic deformation wear in modified medium manganese steel

China Foundry, 2007
A medium manganese steel with high wear-resistance, strength and toughness has been produced with addition of a complex modifier (or refining agent) containing Nb, N, RE and Si-Ca. The results showed that the wear resistance, strength and toughness of the modified medium manganese steel are respectively 1.92 times, 1.45 times and 3.63 times as high as ...
