| Effects of Ni-Cr Based Alloys on the Fiber MetallurgyCharacteristics of Short Cast Iron Fibers |

| 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℃. 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.
