Abstract
Warm rolling experiments on AISI 1015 carbon steel were performed using a duo-reversible mill. The samples have been studied after warm rolling with three deformation ratios by light microscopy and scanning electron microscopy. During the warm rolling pearlite grains are subjected to two simultaneous processes: (i) deformation of the mosaic blocks followed by the separation of some blocks which then appear in the microstructure as fine lamellae pearlite grains, and (ii) deformation of the cementite lamellae which tend to a globular shape within the remaining grains. A slight variation of the hardness across the longitudinal section of the material was evidenced.
Abstract
Es wurde das Halbwarmwalzen eines AISI-1015-Stahls in einem duo-reversiblen Walzwerk mittels Lichtmikroskopie und Rasterelectronenmikroskopie untersucht. Im Laufe des Halbwarmwalzens mit drei Verformungsgraden erleiden die Perlitkörner zwei gleichzeitige Prozesse: (i)Verformung der Mosaikblöcke, von denen sich einige Blockteile abtrennen, die nachher in der Struktur als feinlamellare Perlitkörner erscheinen, und (ii) Verformung der Zementitlamellen zu kugelförmigen Gebilden in den verbleibenden Körnern. Eine leichte Variation der Härte senkrecht zur Längsschnittfläche der Probe ist zu beobachten.
