• 論文の詳細を見る

• The mechanical behavior of an iron carbide base materi al processed by an ingot route was compared with that of the same composition material processed by a pow der route. Thermo mechanical processing routes have been developed to refine the coarse as cast ingot microstructure. Structural refinement is a result of cre ation of strain free regions by carbon dissolution frorn high strain energy subgrain boundaries and slip bands. The ingot processed iron carbide material exhibits su perplastic behavior and deforms by the same grain boundary sliding mechanism as for the powder processed material. It is proposed that thermo mechan ical processing of ingot cast eutectic composition cer amics to achieve a superplastic structure is feasible.
