• This paper deals with formation mechanism of ground white layers in relation to grinding temperature and grinding heat energy. Obtained results are as follows : 1) A ground white layer is formed during a rapid cooling process of a workpiece, which follows the generation of grinding heat energy. 3) The structure Of the ground White layer consists of fine α-phase, α'-phase, fine recrystalized γ_R-phase and fine secondary Fe_3C-phase, Fe_3O_4 and FeO-phase. 3) Hardness of ground white layers is increased because (1) fine untempered martensite contains a greater quantity of carbon in the super-saturated state in the base α-phase, and (2) the fine secondary Fe_3C-phase precipitates.
