Plotting of processing maps of P91 steel and Ms70 brass with energy dissipation and instability parameter computation on the basis of plastometric tests
Original language description
Energy dissipation and plastic flow instability were investigated in P91 steel and Ms70 brass on the basis of continuous tests carried out on Setaram and Gleeble plastometers. Temperature range between 1223 and 1473K and strain rates from 0.0965 to 1.53s-1 were applied for the SETARAM device tested samples, for samples tested on GLEEBLE plastometer the temperatures were from 1073 to 1533K, strain rates varied between 0.1 and 10 s-1. Tests temperatures for the Ms70 brass were 650, 700, 750, 800 and 850degree C. Mathematical evaluation of continuous curves was supported with calculation of larger range of input parameters using the ?sin h? equation. For energy dissipation calculation strain rate sensitivity parameter (m=(d ln?)/(d ln e)) was computed and further the efficiency according to the n=2m/(m+1) formula. Equation E=(gama ln(m/(m+1)))/(gama ln e)+m was utilized for the instability parameter calculation. The results were evaluated using Sigmacon, Gnuplot and Golden Surfer comput
