As-quenched material, namely supercooling material or fast solidification material. Vacuum rapidly quenched technology is a significant method of preparing amorphous and nanocrystalline alloys.
真空快淬材料也叫急冷材料或快速凝固材料，真空快淬技术是制备非晶态金属和纳米晶合金的重要手段。

The no machining directional solidification hollow turbine blades, hollow guide vans and complex structure parts used in aero engine and gas turbine made by vacuum precision investment casting.
Have multiple non-vacuum and vacuum-melting equipment, mainly to the vacuum melting, directional solidification technology and the overall fine-grained technology.
