Textures forming in some steels machined by abrasives

Abstract

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.

Deformation Textures in FCC Metals Subjected to Frictional and to Abrasive Wear

“…In addition, the geometries of torsion tests and sliding wear are too different to expect the formation of the same type of deformation textures. The evolution of surface texture in low-carbon steels during machining by abrasives and superfinishing has been investigated in [11].…”

Texture and Lattice Deformation Pole Figures of Machined Surfaces

“…The analogies were explained by the different amount of thermal energy dissipated into the surface layers of the material during both machining processes. Grinding textures in differently heat treated plain carbon steels were also investigated (Savchuck et al, 1979). While the hardened material state showed no significant changes of the surface texture, weak symmetric machining textures were observed in the other cases.…”
