*PROBABILISTIC COMPUTER SIMULATION OF MARTENSITE*

ABSTRACT:
In bulk polycrystalline materials, the first
nucleation event of a martensite plate within a single grain may induce
transformation in one or more neighboring grains, resulting in a cluster of
partially transformed grains: 'the spread event'. The collection of these
single spread events can be defined as the 'spread' or 'martensite spread'.
First, in this paper, martensite spreads are analyzed to estimate the mean
number of partially transformed grains in a single spread event. Secondly,
taking the quantitative knowledge gained from this analysis as a starting
point, a computer simulation of the martensite spread is proposed. This
computer simulation is carried out in a 3-d network of space-filling grains
represented as Kelvin polyhedra and is based on a probabilistic approach. The
experimental and simulation results are presented, compared and discussed. We
conclude that the probabilistic computer simulation of martensite spread could
successfully describe important quantitative aspects of martensite spread
