摘要

研究了铅黄铜LS59‑1 （Cu-40%Zn-1%Pb， ASTM标准C37000）在400-500 °C等温多向锻造（IMF）过程中的变形行为和显微组织演变。结果表明：在累积应变Σε = 14.4时，IMF有利于形成更均匀、更细晶化的组织，平均晶粒尺寸为2.2 ±0.2 µm，初始状态硬度提高到323 ±21 HV；因此，可以得出结论，在低工艺塑性温度下，IMF导致晶粒组织更有效的细化，β′相发生。

Deformation behavior and microstructure evolution in lead brass during isothermal multidirectional forging

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.
