Effect of Austempering on Plastic Behavior of Some Austempered Ductile Iron Alloys [PDF]

Metallurgical and Materials Transactions A: Physical Metallurgy and Materials Science, 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 ...
