| Abstract: | Flow stress curves of five types of brass were experimently studied with a cam plastometer at a constant deformed speed. The effects of the deformed temperature, determed rate and deformated degree to flow stress were analysed. At the same time, non-linear regressions to mathematical models with different structure were conducted. Through comparision and analysis, mathematical models with higher fitting accuracy were proposed. |
