摘要

采用Ni粉、自合成超细TiC粉和Mo粉制备了综合性能优异的TiC- 10mo - 20ni陶瓷。研究了液相烧结温度(1450 ~ 1525℃)对TiC-10Mo-20Ni陶瓷显微组织和力学性能的影响。结果表明:所有烧结试样均呈现均匀分布的芯-缘结构。随着温度的升高,致密化程度增大,灰色无芯晶粒数量增多。TiC-10Mo-20Ni陶瓷的晶粒尺寸随着温度的升高逐渐增大,平均晶粒尺寸从1.04±0.29 μm上升到1.43±0.55 μm。烧结试样的硬度随温度的升高先升高后降低,在1475℃时达到峰值1622 HV30。断裂韧性(KIC)和横向断裂强度(TRS)随温度升高而增大,1525℃时分别为15.02 MPa·m1/2和1741 MPa。烧结试样主要以沿晶断裂和穿晶断裂的混合断裂模式为主,随温度升高穿晶断裂增加。同时,裂纹扩展和断裂形态变得更加复杂,从而提高了KIC和TRS。

Microstructure and mechanical properties of TiC-10Mo-20Ni cermets

TiC-10Mo-20Ni cermets with outstanding comprehensive properties were fabricated using Ni powder, self-synthesized ultrafine TiC and Mo powders. The effects of different liquid-phase sintering temperatures (1450–1525 °C) on the microstructure and mechanical properties of TiC-10Mo-20Ni cermets were investigated. The results demonstrated that all sintered samples exhibited a uniformly distributed core-rim structure. As the temperature increased, the degree of densification increased, and the number of gray coreless grains increased. The grain size of TiC-10Mo-20Ni cermets gradually increased with temperature, with the average grain size rising from 1.04 ± 0.29 μm to 1.43 ± 0.55 μm. The hardness of the sintered samples initially increased and then decreased with temperature, reaching a peak value of 1622 HV30 at 1475 °C. The fracture toughness (KIC) and transverse rupture strength (TRS) increased with temperature, and had the values of 15.02 MPa·m1/2 and 1741 MPa at 1525 °C, respectively. The sintered samples were mainly dominated by a mixed fracture pattern of intergranular fracture and transgranular fracture, with transgranular fracture increasing as the temperature rose. Meanwhile, the crack extension and fracture morphology became more intricate, thus enhancing the KIC and TRS.
