Abstract
The work examines the deformation behavior and microstructure evolution in lead brass LS59‑1 (Cu–40%Zn–1%Pb, C37000 in ASTM standard) during experimental isothermal multidirectional forging (IMF) in the temperature range of 400–500 °C. The results demonstrate that the IMF facilitates the formation of a more uniform and fine-grained structure with an average grain size of 2.2 ± 0.2 µm, accompanied by an increase in hardness to 323 ± 21 HV in the initial state following an accumulated strain of Σε = 14.4. Therefore, it can be concluded that the IMF leads to a more effective refinement of the grain microstructure at temperatures of low technological plasticity where β′-phase occurs.
