Influence of Austempering Temperatures on the Microstructure and Mechanical Properties of Austempered Ductile Cast Iron

Metals, 2021
The influence of the austempering temperatures on the microstructure and mechanical properties of austempered ductile cast iron (ADI) was investigated. ADI is nodular graphite cast iron, which owing to higher strength and elongation, exceeds mechanical ...

Microstructure and mechanical behaviors of grinding balls produced by dual matrix structure two-step austempering process

Journal of Materials Research and Technology, 2020
The austempered ductile iron (ADI) grinding balls were austenitized at 900 °C for 2 h and then incomplete quenched in a sodium silicate solution for 100 s, after that austempered in an isothermal furnace at 230 °C for 1 h.

Evaluation of CADI Low Alloyed with Chromium for Camshafts Application

Metals, 2022
Different processing routes have been developed to increase the strength and hardness of camshafts for automotive applications. In this work, two carbidic austempered ductile irons (CADIs), alloyed with 0.2 and 0.4 wt% Cr, were evaluated to determine ...

Ausferrite Flake Graphite Cast Iron at the Thermal Fatigue [PDF]

Manufacturing Technology, 2016
The automotive brake (clutch) disks are produced almost exclusively from flake graphite cast iron. These disks must fullfil a variety of strictly controlled parameters - high wear resistance, hardness, resistance against thermal fatigue and good thermal conductivity. The microstructure is created by the IA graphite in pearlite matrix.

Morphology and Crystallography of Ausferrite in Austempered Ductile Iron [PDF]

Metals, 2017
The microstructure of austempered ductile iron was investigated by electron backscatter diffraction technique. The results show that the orientation relationship between acicular bainitic ferrite and austenite is Greninger–Troiano relationship. A single austenite grain is divided into four packets and each packet contains six variants that share a {011}

EFFECT OF ANTIMONY ON THE WEAR RESISTANCE AND IMPACT TOUGHNESS OF CARBIDIC AUSTEMPERED DUCTILE IRON (CADI) [PDF]

European Journal of Materials Science and Engineering, 2022
This work investigated the effect of antimony on the impact toughness and wear resistance of carbidic austempered ductile iron (CADI). Six alloys with a carbon equivalent value of 4.44 (hyper-eutectic composition) were used to evaluate the produced CADI,

Effect of Austempering and Martempering on the Properties of AISI 52100 Steel

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
The mechanical properties of steel decide its applicability for a particular condition. Heat treatment processes are commonly used to enhance the required properties of steel. The present work aims at experimentally investigating the effect of austempering and martempering on AISI 52100 steel. Different tests like microstructure analysis, hardness test,

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]

, 2016
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.
