Material Characterization of Austempered Ductile Iron (ADI) Produced by a Sustainable Continuous Casting–Heat Treatment Process

By controlling the cooling, mean temperature adjustment and isothermal cooling process, bainite and martensite can be produced in the surface and the core of the ductile iron gear using the 75°C hot water as the quenching medium. Since it has a high hardness value in the point and the pitch circle, a low hardness value in the root and the core, this ductile iron can be applied to the actual production of the gear. The gear surface organization will be affected by quenching cooling time. The appearance of the temper phenomenon can result in the decrease of hardness value in the surface of the gear when the cooling time is short..However, the content of the lower bainite can be increased by extending the cooling time properly in the surface of the gear. The influence of the quenching cooling time on the core organization of the gear is small.

Abstract The technology currently used for the fabrication of toothed wheels, gear couplings and chain drums involves the induction hardening process or hardening and tempering after carburising. All these processes take a long time and cause adverse changes in the dimensions and surface quality of products, requiring post-treatment machining to remove the resulting cavities. The paper proposes the implementation of gear elements made of ductile iron with nanoausferritic matrix obtained by a new appropriate heat treatment process. The new material offers good performance characteristics and nearly no need for the application of other technological processes commonly used in the manufacture of gears.

This study is conducted to analyze the effect on the Hardness and Micro Structural Behaviour of three Sample Grades of Tool Steel i.e. EN-31, EN-8, and D3 after Heat Treatment Processes Such As Annealing, Normalizing, and Hardening and Tempering. The purpose of Selecting Tool Steel is Because Tool Steel is Mostly Used in the Manufacturing Industry.This study is based upon the empirical study which means it is derived from experiment and observation rather than theory.
