The Hollomon-Jaffe parameter is usually used to stablish a equivalence between time and temperature in tempering treatment, but not predict the harness of alloy after treatment. In this paper last possibility has been studied. A group cast iron samples was annealed cooled at different rates order obtain with three hardness values. These were tempered using times temperatures. calculated for eac...

the influence of aluminium on the microstructure of austempered ductile cast iron (adi) has been studied. anumber of irons of different compositions have been made by green sand casting and gravity die casting ofappropriate design to provide the experimental materials. austenitising was carried out at different temperaturesand holding times for a variety of experimental irons to achieve suffici...

Microscopic digital volume correlation (DVC) and finite element precoalescence strain evaluations are compared for two nodular cast iron specimens. Displacement fields from \textit{in-situ} 3D synchrotron laminography images obtained by DVC. Subsequently the microstructure is explicitely meshed considering nodules as voids. Boundary conditions applied DVC measurement. Image segmentation-related...
