1Cr10Co6MoVNb钢叶片的成形方法
摘要：
本发明公开了一种1Cr10Co6MoVNb钢叶片的成形方法，其步骤为：先将1Cr10Co6MoVNb钢锭在900℃～1150℃温度区间内制坯、成形，得到叶片锻件；再将加热至700～750℃保温30分钟，随炉冷却至350℃，再空冷至室温；再加热至800～900℃保温30分钟，缓冷至室温；将上述叶片锻件加热至780～850℃进行校正；再缓慢加热至700～750℃保温30分钟后，随炉冷却至350℃，再空冷至室温；再加热至1150～1200℃保温30分钟，油冷至室温；将上述叶片锻件加热至610～640℃保温120分钟，缓冷至室温，重复两次。该方法能够保证叶片锻件的形状、尺寸，提高其力学性能。该方法主要用于航空发动机转子叶片的成形。
摘要（英）：

The invention discloses a method for forming a 1Cr10Co6MoVNb steel blade. The method comprises the following steps: firstly, carrying out performing and forming on a 1Cr10Co6MoVNb steel ingot within a temperature interval of 900-1150 DEG C, so as to obtain a forge piece of the blade; heating the forge piece to 700-750 DEG C, carrying out heat preservation for 30 minutes, cooling to 350 DEG C by a furnace, and then carrying out air cooling to room temperature; then heating to 800-900 DEG C, carrying out heat preservation for 30 minutes, and slowly cooling to room temperature; heating the forge piece of the blade to 780-850 DEG C, correcting, slowly heating to 700-750 DEG C, carrying out heat preservation for 30 minutes, and then cooling to 350 DEG C by the furnace; carrying out air cooling to room temperature, then heating to 1150-1200 DEG C, carrying out heat preservation for 30 minutes, and carrying out oil cooling to room temperature; heating the forge piece of the blade to 610-640 DEG C, carrying out heat preservation for 120 minutes, slowly cooling to room temperature, and repeating the operation twice. By adopting the method, the shape and size of the forge piece of the blade can be ensured, the mechanical property of the forge piece of the blade is improved, and the method is mainly applied to forming of an aeroengine rotor blade.
