product of martensitic transformation in low- to medium-carbon steels with a relatively high Ms temperature; the martensite crystallites have an apperance of tightly arranged thin (less 1 µm) laths separated by low-angle boundaries (see: martensite; compare: acicular martensite), madal/kesksüsinikterastes suhteliselt kõrgel martensiitmuutuse algtemperatuuril Ms moodustunud tihedate kihtidena (alla 1 µm) paigutunud martensiit (vt martensiit; vrd nõelmartensiit)
