“…1, with only slight changes in the characteristic temperatures. In this table are also listed the characteristic temperatures (°C) estimated according to the following formulas where wi (mass%) is the alloying content of element "i": 7) .......... (1) ......... (2) ..... (3) .... (4) These formulas have been calculated using a thermodynamic software and associated databases as previously described. 7) They are thus valid for the low carbon content that prevails at the eutectoid reaction, and account should be made of the presence of graphite that leads to redistribution of all alloying elements but carbon in the matrix.…”

“…Recent interest has been focused on this latter for manufacturing austempered ductile irons (ADI) parts as stressed by a number of works dealing with kinetics of austenitization 1,2) and its physical modelling. 3,4) A clear understanding of the conditions for nucleation and growth of the new phases is necessary for modelling of direct and reverse eutectoid transformations.…”

Describing the conditions for reaustenitization of spheroidal graphite cast irons is of interest for their heat-treatment after casting, e.g. for manufacturing austempered ductile irons. Differential thermal analysis has been used to characterize the direct eutectoid transformation and the reverse transformation, i.e. the reaustenitization. This has been applied to a standard and a Ni-bearing alloy, with a ferritic matrix for the former, both a ferritic and a pearlitic matrix for the latter. The results are discussed in relation with the stable and metastable three phase fields. While earlier description of the direct eutectoid transformation is confirmed, the one for reverse eutectoid has been found more complex and is amended.

Austempered ductile iron is frequently employed in the fabrication of automobile parts due to its good mechanical properties, and its simplicity and low cost of the manufacturing process. The heat treatment design is an important stage, in which parameters such as temperatures and durations are chosen according to the required microstructure, part dimension, and initial characteristics of ductile iron. A coupled thermo-mechanicalmetallurgical model is employed in this work to facilitate the heat treatment design of a ductile iron differential case. The thermal-mechanical model is solved by using a general-purpose software, and the metallurgical model is implemented into it by means of user-defined subroutines. To perform the austempering heat treatment simulation of the part, experimental results were required to complete some basic parameters of the model. In order to select appropriated values of thermal cycle parameters, the numerical model was employed to analyze the influence of austenitizing temperature, and austempering time and temperature in the microstructure, dimensional change of the part, cooling rate, and minimum required time of the heat treatment to obtain a full ausferritic matrix. A good performance of the computational tool was found by comparison of numerical and experimental results.
