This study was employed to characterize the microstructural spheroidisation
and phase transformations of AISI D2 cold-work tool steel at the isothermal temperature during partial remelting method.
Properties of large size cast are dependent of structure metallic base and rate of graphite spheroidisation
. Chemical composition is one of the major factor influencing cast iron mechanical properties.
The research into rapid carbide spheroidisation aims to significantly shorten selected heat treatment processes.

Carbide spheroidisation is a significant metallurgical process which contributes to general changes in microstructure during annealing processes (Nam & Bae, 1999).
Current processes leading to carbide spheroidisation rely on diffusion of carbon in a steel heated to a temperature close to or lightly below [A.sub.c1] (Ghosh S., 2010).
In order to explore the impact of introduced strain on carbide spheroidisation, thermomechanical treatment with subsequent conventional furnace annealing was carried out.
