针对试生产过程中铸件产生的各类缺陷，从其形成机理和影响因素方面进行分析，研究挤压铸造各工艺参数对AZ81镁合金的铸造组织的影响。
Aiming at the various defects in production, the effects of squeeze casting process parameters on AZ81 as-cast microstructure were investigated from formation mechanism and influence factors aspect.
铸件的制作涉及到一些奇怪的老式和新式器械以及烤箱，另外还包括一台架在散落标本抽屉上的老式手工离心机(上图)，它是用来赶走铸件中的空气泡的。
The casts are made using an odd collection of old and new instruments and ovens, including an old handmade centrifuge built on stray specimen drawers (above), used to get air bubbles out of the casts.
在冷却期间或冷却后，把铸件从铸模中取出，然后进行交付。
During or after cooling, the cast part is removed from the mold and then processed for delivery.
