Influence of the Salt Bath Agitation and Austempering Temperature on the Microstructure of Austempered Ductile Iron

, 2017
In this paper the influence of austempering temperature and salt bath agitation on the final microstructure and mechanical properties of the ferritic ductile iron were studied. 17 samples had been subjected to different heat treatment parameters. Different microstructures were recorded upon the completion of the tests.

INFLUENCE OF AUSTEMPERING TIME AND AUSTEMPERING TEMPERATURE IN MICROSTRUCTURE AND MECHANICAL PROPERTIES IN AUSTEMPERED DUCTILE IRON

International Journal of Research -GRANTHAALAYAH, 2020
Austempered Ductile Iron (ADI) has excellent mechanical properties related to its microstructure ausferrite, and with the cycle of austempering heat treatment, many mechanical properties can be obtained from the same alloy, simply changing the time and temperature.

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
