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 ...

Effect of Different Isothermal Time on Microstructure and Mechanical Property of the Low-Carbon Steel Treated by Dual-Stable C-Mn Partitioning Process. [PDF]

Scanning, 2020
The stability of retained austenite was improved by the dual‐stable C‐Mn partitioning process. The phase transformation and element diffusion of dual‐stable C‐Mn partitioning process of tested steel were investigated by means of EPMA, SEM, OM, tensile testing machine, and other analysis methods.

Effect of two-step austempering on fatigue behavior of austempered ductile iron (ADI) [PDF]

SN Applied Sciences, 2019
The effect of two-step austempering on the fatigue properties in alloyed ductile iron was studied. The ductile irons were subjected to conventional and two-step austempering processes. The austempering process was performed by making three batches. In the first batch, samples after austenitizing at 900 °C were conventionally austempered separately at ...

Tempering and Austempering of Double Soaked Medium Manganese Steels

Frontiers in Materials, 2021
The addition of a tempering or austempering step to the double soaking of a 0.14C–7.17Mn (wt pct) steel was investigated in the present contribution. The double soaking heat treatment is a two-step intercritical annealing heat treatment, which generates ...

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.
