Experimental Study of Rheological Properties of Fe-C-O-Cr alloys
Original language description
Rheological properties (dynamic viscosity, flow curves) of selected Fe-C-O-Cr alloys were experimentally investigated with the use of a high-temperature rotating viscometer Anton Paar FRS 1600. The viscosity of concerned alloys was measured during cooling at a rate of 2.5 oC/min. The maximum temperature achieved within experiments was 1,550 oC. The flow curves were recorded at this temperature to assess flow properties. According to their shape, all alloys exhibited non-Newtonian behaviour. At the temperature of 1,550 oC, the alloys behaved as shear thickening fluids. Given that viscosity depends mainly on the change in temperature and chemical composition, these aspects were considered in this work. Two series of model Fe-C-O-Cr alloys, which differed in chromium (0.924 wt.% - 4.795 wt.%) and carbon (0.042 wt.% - 1.378 wt.%) content, were selected to examine the influence of these elements. In the given concentration ranges, only slight dependence of viscosity on chromium and carbon content was found. Further, the viscosity increased exponentially with decreasing temperature at measured temperature intervals of 1,550 oC - 1,450 oC (1,350 oC).
