Abstract
New variant of grouping of martensite platelets was observed experimentally for the
and
martensites. This variant represents a closed rhombic bipyramid faced eight habit planes of the same type united around one
common direction
. The space of an austenite grain is filled by joining bipyramids with common edges into larger bipyramids of the next hierarhical
level. Different variants of outgrowing faces in pyramidal groups in combination with different sectioning plane of the specimen
allow to explain all observed morphological variants of the grouping martensite.
