摘　　要：The liquid sintering characteristics have been studied in the sintered compacts of short cast iron fibers added with Ni-Cr based alloy powder at the sintering temperature of 1100 degrees C. With the increase of Ni-Cr based alloy content, the microstructure of sintered compact of short cast iron fibers transformed from pearlite + ferrite to martensite + austenite, meanwhile volume expansion appeared in the sintered compact, leading to more pores. The proper addition of P-Fe powder could restrain the expansion of the sintered compact and increase the strength and hardness of the sintered compact.The liquid sintering characteristics have been studied in the sintered compacts of short cast iron fibers added with Ni-Cr based alloy powder at the sintering temperature of 1100 degrees C.
