چکیده
Abstract Solid-state transformation during heat treatment is of great practical importance because it significantly affects the final structure, properties, and thermal stability cast components. The present study highlights issue structure formation its effect on high-quality iron, namely, austempered ductile iron (ADI). In this study, experiments were carried out for castings with a 25-mm-walled thickness under variable conditions, i.e. , austenitization austempering within ranges 850 °C to 925 250 380 °C, respectively. X-ray diffraction (XRD) investigations range − 260 + 450 parameters related XRD tests, which provided information phase participation, lattice parameters, stresses in microstructure as well an expansion crystal lattice. results also provide insight into role homogeneity ADI iron. work aims develop strategies suppress blocky-shaped austenite maintain homogeneous high stability.

Effects of Carbides on Fatigue Characteristics of Austempered Ductile Iron
Crack initiation and growth behaviour of an austempered ductile iron (ADI) austenitised at 800C and austempered at 260C has been assessed under three point bend fatigue conditions. Initiation sites have been identified as carbides remaining from the as cast ductile iron due to insufficient austenisation. The number of carbides cracking on loading to stresses greater than 275 MPa is critical in ...

متن کاملDevelopment of High Silicon Dual Phase Austempered Ductile Iron
This work deals with the feasibility of obtaining Austempered Ductile Iron with Dual Phase structures (DPADI) through heat treatment, starting from different as-cast microstructures. The mechanical properties on these microstructures were evaluated. DPADI microstructures were obtained by adding different tenors of silicon (2.4% to 4.2%) to the melts and keeping the other alloying elements const...
متن کاملThe Bainite Reaction Kinetics in Austempered Ductile Iron
Bainitic reaction kinetics in ductile iron contained according to Ukrainian standard (weight %) 3.603.80 carbon, 2.60-2.80 Si, 0.12 Mn, 0.60 Cu and additionally alloyed by Mo (0.15-0.20) has been studied. It was found that the overall transformation kinetics becomes slower as transformation temperature increase. This is because more intensive redistribution of carbon into austenite at higher te...
