In the present experimental study, the influence of primary martensitic structure on acceleration of graphitization process in hypereutectoid steels during subsequent heat treatment cycle was investigated by using of optical microscopy (OM...

Graphitization process in steels can be performing for wear resistance improvement. During this procedure cementite dissociated to free carbon (graphite) and ferrite and finally a ferritic matrix is produce-able. Although graphite gives good...

Graphite is one of the main phases in the structure of most cast irons whose shape,

morphology and distribution have a significant effect on the mechanical properties of cast

irons. In present research, the presence of graphite...

Graphene oxide -GO- is a chemical oxidized of graphite carbon material, including hydroxyl,
carboxyl, carbonyls or epoxides functional groups [1, 2]. The presence of these groups on the
GO surface provides reactive sites for the immobilization...

graphitisation process by annealing primary martensitic structures at 670uC. Graphite phase

evolution during graphitisation treatment was investigated by light optical and scanning electron

microscopy and energy...

In this research, graphitization transformation of commercial hypereutectoid steel called ck 100 was studied by the dilatometric experiments at the range of 600 – 700 ℃ from prior martensitic structure. Also the effect of quenching media...
