REAL TIME-TEMPERATURE MODELS FOR MONTE-CARLO SIMULATIONS OF NORMAL GRAIN-GROWTH

Two different models for the simulation of normal grain growth in meta ls and alloys are presented. These models demonstrate the application of real time-temperature based Monte Carlo (MC) simulation to material s processing. A Grain Boundary Migration model coupled the MC simulati on to a first principle grain boundary migration model. The results of this simulation were shown to correlate well with the experimental re sults for isothermal grain growth in zone refined tin. An Experimental Data Based model coupled the MC simulation with experimental grain gr owth data. The results from this simulation were shown to correlate we ll with the grain growth during continuous heating of a beta titanium alloy. Copyright (C) 1996 Acta Metallurgica Inc.
