Yi. Ustinovshchikov et al., INITIAL-STAGES OF DECOMPOSITION OF SOLID-SOLUTIONS IN IRON - TITANIUMAND IRON - NIOBIUM ALLOYS, Russian metallurgy. Metally, (4), 1993, pp. 202-205
The structural investigation of alloys of the Fe - n and Fe - Nb syste
ms has been carried out. The formation of Laves phases proceeds throug
h the stage of forming the tweed structure with a periodic alternation
of regions enriched in and depleted of an alloying element, Anomalous
change in the properties of the alloys is established:the formation o
f the tweed structure is accompanied by the decrease of the alloy hard
ness.
