Corrosion fatigue of austempered ductile iron

Journal of Materials Science, 2003
Corrosion fatigue (CF) behavior has been investigated for an austempered ductile iron (ADI) by conducting systematic fatigue tests at 20 Hz, including both high-cycle fatigue (HCF, S-N curves) and fatigue crack growth (FCG, da/dN-ΔK curves), in air, lubrication oil and several aqueous environments.

Austempering of low manganese ductile irons

Materials Science and Technology, 1993
AbstractX-ray diffraction, optical microscopy, and hardness measurements were used to determine the austenitising kinetics and the stage I and stage II austempering kinetics of a low Mn, Cu iron and a low Mn, Ni–Cu iron during austempering at 300, 370, and 440°C after austenitising at 900, 950, and 1000°C.

Machinability of alloyed austempered ductile iron

International Journal of Machine Tools and Manufacture, 1995
Austempered ductile iron (ADI) has found enormous applications in recent years due to its high strength and hardness, coupled with substantial ductility and toughness. The high strength and hardness of ADI have caused many researchers and engineers to doubt the machinability of this material.

Engineering Austempered Ductile Iron Castings

2022
Abstract Unlike conventional quench and temper heat treatment, austempering is an iron and steel heat-treatment process that enhances mechanical properties through the isothermal transformation of austenite with a minimum amount of quenching stresses. This chapter begins with a discussion of austemperability requirements.

Fracture Studies of Austempered Ductile Iron

2021
Austempered ductile iron (ADI) represents wide segments of engineering applications. In the present investigation, Single edge notch bending (SENB) samples austempered at 300 °C for 120 minutes duration were subjected to three-point bending test to evaluate the plane strain fracture toughness (KIC) of ADI. The presence of crack in mechanical components

Wear Properties of Austempered Ductile Irons

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">Austempered cast irons have a unique microstructure (ausferrite) that provides for excellent wear properties. This paper will examine the available data in the literature on wear in several modes: abrasive wear, adhesive wear (frictional or sliding and rolling), and erosive wear.

Austempered Ductile Iron (ADI): A Review

Materials Performance and Characterization, 2016
Abstract Austempered ductile iron (ADI) is a group of ductile irons offering the design engineers remarkable mechanical properties. It exhibits an excellent combination of high strength, ductility, toughness, fatigue strength, and exceptional wear resistance that is unavailable in other grades of cast iron.
