Extension of grains in the direction of rolling occurs and the arrangement of crystallographic lattice getsa directional haracter. Banding character of other structural phases, such as of inclusions, pearlitic blocks, etc. has been developed too. Three types of texture (. deformation, structuraland crystallographic texture) arise, which yields in a directional character of mechanical roperties – see Fig. 1 [9]. Heat treatment is included after cold forming for removal of anisotropy of properties. To factors influencing the final character of microstructure after annealing belong most importantly: the initial character of material structure before cold forming, the total cold reduction,annealing conditions (temperature and time) and also coolingspeed [1,5,6,7,10,13,15,17, 18, 19]. More and more progressive types of material have been used in this field of processing – see . [2,3,8,11,16]. As a whole, the more cold deformation of aterial before annealing, the lower initial temperature of recrystallization. At low temperatures the time necessary for finishing of recrystallization is much higher and the requiredspheroidizing of carbides cannot be pleted [4].

Illustration of origin of deformation textures of metal [9]Strength or hardness properties of material generally decrease with increasing temperature of annealing, whereas plastic properties increase. Substantial lowering of strength values occurs at temperatures which are close to 600 176。 ?? roll barrel 110 mm。C within 80 minutes, cooling from 1200 to 400 176。rek, E. M237。?ek, . Dobrza??ski, S.
