摘 要:<正> Nickel,as the carrier through which Fe atomsdiffuse,obviously enhances the densification ofsintered compact containing short cast iron fibre.When Ni content is above 4.5 wt-% there are someaustenites in microstructure at room temperature,discontinuous cementite networks at the interfacesbetween austenites and pearlites,free graphite pre-cipitated in austenite and pores andWidmannst(?)tten carbide precipitated in austenite.When Ni content is about 12 wt-%,it leads to de-crease in densification ratio and change in fracturemorphology of sintered compact from ductile tobrittle.
