Influence of Austempering Temperature on Microstructure and Mechanical Properties of High‐Silicon Carbide‐Free Bainitic Steel

steel research international, Volume 94, Issue 9, September 2023., 2023
In this article, Franceschi et al. study a newly developed medium carbon high silicon carbide free baintic steel. The effect of different is isothermal transformation temperature on the bainitic microstructure is investigated in terms of phase constituents, morphology and mechanical properties. It is observed that the isothermal treatments below 300 °C

Ab Initio Study of Alloying Impact on the Stability of Cementite in Transformation‐Induced Plasticity‐Assisted Advanced Steels

Advanced Engineering Materials, Volume 24, Issue 11, November 2022., 2022
Ensuring the transformation‐induced plasticity (TRIP) effect in advanced high‐strength steels (AHSS) requires that the formation of cementite is suppressed by the addition of alloying elements such as Si. Theoretical simulations reveal the impact of alloying elements on the elastic and chemical stability of cementite, taking into account the role of ...

Nanobainite Generated in Low‐ and Medium‐Carbon Steels via an Economical Alloying Strategy

steel research international, Volume 93, Issue 6, June 2022., 2022
A low‐cost strategy for generating low‐ and medium‐C steel alloys relying on Al additions to accelerate the transformation is investigated. Increasing Al in isothermally and continuously cooled conditions refines the lamellar thickness, lowers both the incubation and transformation times but causes a slight drop in tensile properties.

Tooth Root Bending Fatigue Performance of Shot Peening TM210A Steel Spur Gear

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
Tooth root bending fatigue performance is the primary consideration in gear design. To investigate the difference between the tooth root fatigue performances of shot peened and base material, TM210A steel gears and double‐tooth pulsating bending fatigue experiment with a stress ratio of 0.05 was carried out on the experimental gears by the group method

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.

Diffraction-based determination of single-crystal elastic constants of polycrystalline titanium alloys. [PDF]

J Appl Crystallogr, 2019
The single‐crystal elastic constants of polycrystalline titanium alloys have been determined using neutron and synchrotron powder diffraction.Single‐crystal elastic constants have been derived by lattice strain measurements using neutron diffraction on polycrystalline Ti‐6Al‐4V, Ti‐6Al‐2Sn‐4Zr‐6Mo and Ti‐3Al‐8V‐6Cr‐4Zr‐4Mo alloy samples.

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 ...
