High-angle boundaries arising with phase transformations

A calculation was made of the disorientations between the colonies (grains), formed from the new phase nuclei connected with the matrix phase by different crystallographically equivalent variants of the operating orientational relationship. Calculations were made for the FCC reversible BCC, BCC reversible HCP, FCC reversible HCP phase transformation. A comparison was made of the spectrum of disorientations calculated with the special disorientations and with experimental data
