Back calculation of parent austenite orientation using a clustering approach

Figure 2
Each b.c.c. orientation (variant) denoted by ` [alpha]

', gives a set of 12 and 24 potential f.c.c. parents, based on the N-W and K-S ORs, respectively, denoted by the column `V [gamma]

_i'. Each cluster with the minimum summation of mutual misorientation angle, min(SMMA), is generated by associating a group of V [gamma]

with one member drawn from each set. (Here [gamma]

emphasizes that we refer to the parent phase.)
