Furthermore, continuous attempts are being implemented to enhance the yield strength of coniv mea. Upon removal of fe, the equimolar coniv mea annealed below 800°c attains a nearly pure κ phase structure, resulting in substantially reduced strength (below 250 mpa) and extremely poor ductility less than 1% (16, 26, 27). However, so far, the hot processing maps for coniv mea have not been investigated and the optimum processing window of coniv mea is still unknown In this study, the hot deformation behavior of fcc coniv mea is systematically investigated. Coniv medium entropy alloys (meas) have been widely recognized for their superior corrosion resistance Nonetheless, their extensive application has been hindered by high production costs and complex fabrication processes.
