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.

Carbidic austempered ductile irons

2017
Carbidic austempered ductile iron, which attracts considerable attention in wear applications recently, due to its superior abrasive wear resistance and sufficient impact toughness, is the latest member of ductile iron family.  A new technology and additional investment are not required for the production of these irons.
