Microstructure and Texture Development in Thermomechanically Processed Leaded Brass

Leaded brass alloys with high zinc content are classified as dual-phase (?-??) alloys. For these alloys, ?-?? phase transformation induced by thermomechanical processing (TMP) is expected to play a significant role not only in the formation of ? and ?? phases uniformity lead particles but also development ?3 boundaries their variants phase. To assess such impact, current study has employed two TMP schemes, each scheme consisting four cycles compression annealing. Samples first (TMP-1) were annealed at 670 °C promote from ??, compared second (TMP-2) samples 525 °C. Microstructure examination indicated that TMP-1 fostered remarkable growth area fraction phase, accompanied grain coarsening phases. This resulted isolation grains less interaction trip junctions, therefore, reduction occurred On other hand, TMP-2 successfully enhanced cluster grains, enabling further generation via strain-induced boundary migration mechanism ultimately leading breakup random network. In addition, schemes limited particles. Most located ?-?? interfaces, which suppressed particle-dragging effect. both initial texture tension fibers was largely preserved after for ?? Nevertheless, produced randomization due increasing boundaries.
