- Surface grain refinement of turbine blades in Ni based superalloy K18 were studied by comparison of experimental results in different alloys and mold surface materials. 选用K18合金和纯金属镍及不同的面层细化料,通过实验对比研究了镍基高温合金叶片表面晶粒细化机理。
- The results indicate that the surface grain size of the steel sheets is smaller than that of the center by batch annealing, while it is on the contrary of the steel sheets by continuous annealing. 结果表明，罩式退火后钢板表面晶粒比心部的细小，而连续退火后钢板表面晶粒比心部的粗。
