采用火花等离子烧结（SPS）法制备了不同碳化钛浓度（0.05、0.1、0.25、1）wt.%的W-K-TiC合金。进行了5 ms的单次热冲击试验和1 ms的100次热冲击试验。研究了各试样的显微组织和维氏显微硬度。结果表明，热冲击试验后试样表面开始再结晶，由于热冲击试验后试样表面温度较高，单次5ms的试样表面再结晶比单次1ms的试样表面再结晶更严重。样品分别在1400℃、1600℃、1800℃退火。结果表明，TiC颗粒的加入可以减缓W-K-TiC合金的再结晶，其再结晶温度可达1400 ~ 1600℃。
W-K-TiC alloys with different titanium carbide concentration (0.05, 0.1, 0.25, 1) wt.% were fabricated through spark plasma sintering (SPS) method. Single shot thermal shock tests with a length of 5 ms and 100 shots thermal shock tests with a length of 1 ms were carried out. The microstructure and Vickers micro-hardness of each sample were investigated. It is revealed that the surface of the samples began to recrystallize after thermal shock tests, and the samples with 5 ms for single shot had more serious recrystallization than the samples with 1 ms for 100 shots because of its higher surface temperature after thermal shock tests. The samples were annealed at 1400 °C, 1600 °C, 1800 °C, respectively. It is shown that the addition of TiC particles could slow down recrystallization of W-K-TiC alloy, and its recrystallization temperature can reach to between 1400 °C and 1600 °C.
