Abstract
In this paper, the results of investigations into, and of the analyses of, the hot deformation behaviour of the Ni50Cr45N0.6 alloy were presented. Compression tests were conducted on a Gleeble 3800 thermo-mechanical simulator within the following temperatures range 850-1200 degrees C and within that of the strain rate 1-40 s(-1) to the constant true strain of 0.9, for the purpose of fulfilling the objective of obtaining experimental stress date. Those data were taken advantage of for the purpose of calculating the workability parameters, and that means the efficiency of power dissipation., the flow instability. and the strain rate sensitivity m. The processing maps based upon Murty's criterion were drawn up for the following true strain range: 0.2-0.9, and, subsequently, both processing windows and the flow instability areas were determined. For the alloy being analysed, the most advantageous conditions of metal forming were ascertained within the following range of temperatures: 950-1000 degrees C, and for that of the strain rate amounting to 10-40 s(-1), and that because of (occurring at the temperature of 950 degrees C) the peak of the efficiency of power dissipation parameter., amounting to 22% (in accordance with Murty's criterion). The flow instability areas identified on the processing maps ought to be avoided in metal forming processes. Experimental rolling tests were also conducted.
