CARBIDE FORMATION IN AUSTEMPERED DUCTILE IRON ALLOYED WITH NICKEL AND COPPER

FA N Zhikang (Xi'an University of Technology , China)SMALLMANRE(University of Birmingham , UK Manuscript received 3 January 1995)

金属学报(英文版)

Carbide formation in austempered ductile iron (ADI) alloyed with Ni and Cu has been studied by use of TEM. The results show that η carbide precipitates in the bainitic ferrite when austempered at 350℃.for 6h, but no carbide was found at the austenite/.ferrite interfaces. When austempered at 300℃, tw...
