报道了俄国航空材料研究院(ВИАМ)在定向单晶高温合金组织控制方面的最新研究成果,例如,利用高速定向结晶工艺创造具有单晶组织的宽弦叶片,以及制造前后缘为规定位相的单晶,而在叶身中部为细柱状定向结晶组织的复合组织叶片。这些新工艺提高了材料的工作能力和发动机寿命。 Reported the latest research results of the Russian Aeronautical Materials Research Institute (ВИАМ) on the control of directional single crystal superalloy structure. For example, the use of high-speed directional crystallization process to create a single-crystal wide-chord leaves, as well as the production of a single phase Crystal, while in the middle of the blade body for thin columnar oriented crystalline structure of the composite tissue blades. These new processes increase the material’s ability to work and the engine’s life.
