Zusammenfassung:	The invention discloses a blade and a preparation process thereof. The preparation process comprises the following steps that primary vacuum stress relief annealing is carried out on a blade forge piece after a correction procedure of blade profile forming of a precision forging blade; the blade forge piece is machined; secondary vacuum stress relief annealing is carried out on the machined blade forge piece; and shot blasting and vibration finishing are carried out on the blade forge piece subjected to secondary vacuum stress relief annealing, and preparation is completed. 本发明公开了一种叶片及其制备工艺，包括如下过程：在精密锻造叶片叶型成型的校正工序后，对叶片锻件进行一次真空消应力退火；再对叶片锻件进行机械加工；对机械加工后的叶片锻件进行二次真空消应力退火；对二次真空消应力退火后的叶片锻件进行喷丸和振动光饰，制备完成。
