| Abstract Scope |
Microstructure and mechanical properties of Ti(C, N)-SUS316L stainless steel cermet have been investigated. The mechanical properties (3-point bending strength, hardness and fracture toughness) were evaluated using the dense samples sintered at 1550°C for 4 h in Ar gas atmosphere． The microstructure and mechanical strength were affected by the nitrogen content (x) in Ti(C1-xNx) . Up to x=0.5, the flexural strength of sintered samples containing 10 vol.% SUS increased to 1060 MPa with a decrease in the particle size of Ti(C, N) phase. In the case of the sample having x=0.7, the strength lowered to 900 MPa due to an increase in pores. The mechanical strength and fracture toughness of samples increased with the volume of SUS. The flexural strength of the x= 0.5 sample containing 20 % by volume of SUS exceeded 1100 MPa and fracture toughness measured by SEPB method was 14 MPa·ｍ1/2. |
