Steel in Translation Aims and scope

Abstract

The Co–28Cr–6Mo medical alloy after homogenization is tested in uniaxial compression at temperatures of 1000, 1100, and 1200°C and strain rates of 1, 10, and 50 s–1 using the Gleeble System 3800. The stress-strain curves describing the deformation behavior of the alloy are obtained. Using three models (power-law, exponential, and hyperbolic sine function) describing the flow stress, hot deformation parameters are calculated (activation energy and Zener–Hollomon parameter). The results of calculations based on the power-law and hyperbolic sine functions show the highest degree of convergence. These models can be used to accurately calculate the flow stress for given parameters of temperature and strain rate or to simulate the deformation process. Also, based on processing maps, the strain-rate modes of hot deformation of the Co–28Cr–6Mo alloy are developed, which will make it possible to select the optimal rolling modes in the future. According to the data obtained, as strain accumulates, the favorable temperature-rate conditions for hot deformation shift to the region of high temperatures and low strain rates. In this case, the extremely unfavorable zone with negative values of the plastic flow stability criterion ξ, which appears at values of the deformation parameter e = 0.3–0.4, continues to grow quite significantly with increasing strain. Hot deformation of the Co–28Cr–6Mo alloy at low compression ratios (e < 0.2) is more appropriate at temperatures above 1150°C and strain rates of at least 20 s–1. As the degree of deformation increases, lower strain rates (1–5 s–1) and higher deformation temperature should be used.
