对1Cr18Ni9Ti—20g热轧复合中板分别加热到不同温度空冷、水冷和随炉缓冷处理,研究基体与复层的组织特点和复合板的性能。研究结果表明采用加热到980～1020℃空冷固溶处理,既能保证基体的力学性能,又能使复合材料得到较好的耐蚀性。使1Cr18Ni9Ti—20g热轧复合中板得到较好的综合性能,其前提是通过热处理使基体得到随机分布的铁素体和珠光体组织,使复合层有TiC析出。 1Cr18Ni9Ti-20g hot-rolled composite plate were heated to different temperatures air-cooled, water cooled and furnace slow cooling treatment to study the matrix and the stratified microstructure and composite properties. The results show that the use of heated to 980 ~ 1020 ℃ air-cooled solution treatment, both to ensure the mechanical properties of the matrix, but also make the composite get better corrosion resistance. 1Cr18Ni9Ti-20g hot-rolled composite plate to get a better overall performance, the premise is that the matrix by heat treatment to get ferrite and pearlite random distribution of the organization, the composite TiC precipitation.
