Sažetak
In shorter time the forming temperature is getting by heating-up material before forming and this is without exposure surface and inside quality of heating sphere. The well choosing forming temperature is leading to rise the technology of formability during reducing of deformation resistance in forming, it has good influence in term of energetically severity, working life of forming tools and forming productivity. The diffusion procedures and reducing of density of grid breakdown by rising of temperature and the quality of grain boundaries is getting better. The experiment was specialized to analyse of influence heating to the structural properties of material, that is mean determine grain size after different conditions of samples heating (different temperatures, time) and persistence to improve quality of heating steels that was Cr and Mo alloyed to prevention of the rift creation by sequent rolling these marks of steels. The results of experiment were elaborated and verified by mathematical relation that analyse grain growing with view to temperature and heating time.
