The texture formation, at each machining stage, in the CT45, CT50 and CT40X steels machined via two technological alternative ways has been investigated, these being as follows: (1) turning — grinding — superfinishing, (2) turning — hardening — grinding — superfinishing. Presented are the (110) pole figures obtained by the reflection method. It was shown that the grinding and superfinishing of the specimens in compliance with the alternative way 1 led to formation of the texture, the basal ideal orientations of which resemble that of rolling one for the [Russian Text Ignored].‐metals. The recrystallization (110) [001] component is therewith also contained in the grinding texture. No texture was recognized in specimens machined by the procedure according to the alternative way 2. These facts being accounted for by the pressure and temperature factors operating in the course of grinding and superfinishing, as well as by the dependence of the deformation mechanism of the steels under study on a preliminary machining of the latter.

Cold Rolling Texture Development in Zn, Cd and MgStudied are the regularities of preferred orientations in the process of rolling of zinc, magnesium, and cadmium. On the basis of the data obtained and analysis of crystallographic mechanism of Cd, Zn and Mg crystals a "dynamic" model of the rolling texture formation in zinc and cadmium as well as a "monotonic" one in magnesium are suggested.Es werden die GesetzmiiBigkeiten bevorzugter Orientierungen beim Walzen von Zink, Magnesium und Cadmium untersucht. Auf der Grundlage der erhaltenen Werte und einer Analyse des kristallographischen Mechanismus von Cd-, Zn-und Mg-Kristallen wird ein ,,dynamisches" Model1 der Walztexturbildung in Zink und Cadmium sowie ein ,,monotones" fiir Magnesium vorgeschlagen.The rolling texture of the hexagonal close packed metals has been the'subject of a much recently carried out investigation. It has been found that the texture in Ti (MOROZ, BRJUKHANOV, IVANIJI), Zn (MOROZ, BRJUKHANOV, IVANIJI, ALSAGAROV, ADAMESKU, GELD) as well as in Be (KAPRHERIN, PAPIROV, TIKHINSKIJ) at starting and medium stages of deformation featured the presence of a feeble orientation and the more extensive (0001) f a[lOiO] component developing in the rolling process at the expence of the (0001) component and a random portion available.At N S 0 -9 0~0 RA the basal component disappears and the texture is delineated by an inclination of the basal plane with respect to the SN a t an angle of 25" for Zrl), 30-40' for Ti, and 25-30' for Be (KAPCHERIN, PAPIROV, T~HANSKIJ). The texture of other hexagonal close pooked metals is as yet imperfectly understood, the final orientations being only known as formed upon imposing the high-degree deformations (WASSERMAN, GREVEN). The texture in Co (EPPELSHKIMER, WILCOX) and Mg (BAKA-RIANI) at 70-90y0 RA is nearly similar to that of the basal one. The textures in DY and Hf (EPPELSHEIMER) hold an intermediate position between those of Be and Ti. The texture of Cd was the subject of only two investigations carried out by rather out-of-date methods. According to the data of SCHMID, STABELBACH the hexagonal axises in cadmium rolled up to the high-degree deformations are departed a t an angle of 60" from the sheet normal (SN), while for a heavy-rolled cadmium some authors (SCHMID, WASSERMAN) give a pole figure according to which the basal plane in the SN-RD plane is departed from the SN through 25-30".More comprehensive the zinc texture is studied. According to the data by SCIIMID, STOFELBACH, VALOUCH the texture of heavy-rolled zinc features the (0001)f aSN-RD [IOlO] TD orientation i.e. similar to the texture of metals having a C / U ratio less than l) The data concerning an angle a for Zr are greatly conflicting ones and show a scatter over 20" to 40" range (see for example, (MOROZ, BRJUKHANOV, IVANIJ; ALSAQAROV, ADA-MESKU, GELD) and (KEELER, HIBBARD, DECEER; GEARY, LUSTMAN). This, as it is shown by MOROZ, BRJUKHANOV, NICHIPORENKO, IVANIJ, is associated with an effect of the texture "inheritance". The values of an angles a = 23-26" ar...
