Tribological Characteristics of GCI‐EN31 Steel Surface Contact with Dry Sliding Condition

Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022
Grey cast iron (GCI) and steel contact surface application is an inevitable component and provides good wear resistance in several applications, not only in automobiles. Grey cast iron consists of a predominantly pearlitic/ferrite matrix or both with graphite flakes.

[Retracted] Study of Surface Roughness of Cutting Isothermally Hardened Ductile Iron in Tosa Knife Forging Technique Based on Intelligent Calculation

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
With a long history of more than 600 years of development, the Achang Tosa knives have always been handmade and made in strict accordance with tradition and absorbing the essence of foreign cultures. It is not only a tool or a gift, but also a “knife culture” and a local “folk culture” with local ethnic characteristics in Yunnan.

A Unique Quenching and Deformation Dilatometer for Combined In Situ Neutron Diffraction Analysis of Engineering Materials

Advanced Engineering Materials, Volume 23, Issue 11, November 2021., 2021
A modified quenching and deformation dilatometer (TA instruments DIL 805A/D/T) is now in operation at the Heinz Maier‐Leibnitz Zentrum (MLZ, Germany) neutron center. It is customized for running neutron scattering measurements during the temperature/deformation treatment of the sample, in particular neutron diffraction (phase, texture, and lattice ...

Influence of different electron beam surface pre‐treatments on the results of subsequent boriding‐part I Einfluss verschiedener Elektronenstrahl‐Randschichtbehandlungen auf das Ergebnis eines nachfolgenden Borierens‐Teil I

Materialwissenschaft und Werkstofftechnik, Volume 52, Issue 8, Page 815-830, August 2021., 2021
Under comparable boriding conditions, the layer thickness generated on the unalloyed cast iron surface were approximately twice as thick as on the nickel cladded surface. For the unalloyed substrate, the well‐known iron borides were determined. The boride layer formed on the alloyed surface contained iron borides with dissolved nickel portions as well ...

Microstructure and mechanical properties of manganese-alloyed austempered ductile iron produced by novel modified austempering process

Cogent Engineering, 2022
Austempered ductile iron (ADI) has numerous applications because it is lightweight and has excellent mechanical properties. However, although the ADI obtained by the traditional austempering process possesses high strength and hardness, it has low ...

Micromechanical simulation of fatigue in nodular cast iron under stress‐controlled loading

Material Design &Processing Communications, Volume 3, Issue 4, August 2021., 2021
Abstract Nodular cast iron contains about 10 vol% of graphite particles, which debond easily and thus act as nucleation sites of voids. When an elastic–plastic porous material is subjected to cyclic loading, voids grow with each load cycle due to so‐called void ratchetting until the micro‐ligaments between the graphite particles begin to neck.
