HIGH-TEMPERATURE WEAR-RESISTANT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a high-temperature wear-resistant member which is difficult to have occurrence of chipping and is capable of keeping high-temperature wear resistance over a long period.SOLUTION: A high-temperature wear-resistant member is composed of a single crystal alloy or a one-directional solidification alloy of an Ni-based dual-phase intermetallic compound, is difficult to have occurrence of intergranular fracture, compared with members composed of conventional Ni-based dual-phase intermetallic alloy, substantially reduces occurrence of chipping and is capable of keeping the excellent high-temperature wear resistance of the Ni-based dual-phase intermetallic compound over a long period.
