Austempered Ductile Iron Machining
Technological Engineering, 2015 Abstract This article deals with the machining of cast iron. In industrial practice, Austempered Ductile Iron began to be used relatively recently. ADI is ductile iron that has gone through austempering to get improved properties, among which we can include strength, wear resistance or noise damping.

Evaluation of Volume Fraction of Austenite in Austempering Process of Austempered Ductile Iron [PDF]
Metals, 2019 In the present work, an evaluation of the volume fraction of austenite in austempered ductile iron (ADI) is presented by means of three different methods. Experimental tests were conducted on ADI samples after different austempering conditions and contained different volume fractions of the phase components in the metallic matrix (ferrite plates ...

Effect of Austempering on Plastic Behavior of Some Austempered Ductile Iron Alloys
Metallurgical and Materials Transactions A, 2011 A numerical description relating microstructure to elastic and plastic deformation behavior would make it possible to simulate the mechanical behavior of complex cast components with tailored material properties. Limited work and data, however, have been published regarding the connection between microstructure and plastic behavior of austempered ...
