It is shown that the addition of 0.01 wt.% of Ti–TiC modifier synthesized by the method of high-voltage electric discharge treatment of Ti powders in kerosene and briquetted with the help of spark plasma sintering makes it possible to reduce the grain size from 1–2 mm to 0.2–0.6 mm in all modified specimens of SM88U heat-resistant alloy. In this case, the tensile strength of modified specimens at a temperature of 900°С is 65–69 MPa and their long-term strength increases, on the average, by 20%.

Ti-TiC系改性剂的脉冲放电制备及其对金属结构和性能的影响

结果表明，加入 0.01 wt.% 的 Ti-TiC 改性剂，通过在煤油中高压放电处理 Ti 粉末的方法合成并借助放电等离子烧结压块，可以减小晶粒尺寸。在 SM88U 耐热合金的所有改进试样中为 1-2 毫米至 0.2-0.6 毫米。在这种情况下，改性试样在 900°С 温度下的拉伸强度为 65-69 MPa，其长期强度平均增加 20%。
