显微组织

①锻件大裁面处(检验非金属同化、晶粒度）

②零件的高应力部位(检验同化、晶粒度、过热）

③锻件变形激烈、温升严里处(检验过热和晶粒度）

④铝合金锻件检验过热、过烧，应在其小裁面并凑近其外貌部位取样

无损检验：

对解放锻件举办无损检验，要紧用超声波探伤，有些锻件也可在粗加工后用荧光渗透、磁粉深透、X—射线等无损检验法。超声波检验分为全面检验和分区检验两种。分区检验是在锻件上的差别部位采取差别灵敏度等级的标准举办尝试。区域的划分应合乎零件图样的要求，并在锻件图样中做出响应的规定。

Microstructure

金满地45451cc1 Forging large cutting surface (testing non-metal assimilation, grain size)

金满地45451cc2 high stress parts of the part (test assimilation, grain size, overheating)

金满地45451cc3 Forgings are intensely deformed and the temperature rises to the extreme (testing overheat and grain size)

金满地45451cc4 aluminum alloy forgings are tested for overheating and over-burning. They should be sampled on their small cuts and close to their appearance.

Non-destructive testing:

金满地45451ccFor the non-destructive testing of liberation forgings, it is necessary to use ultrasonic flaw detection. Some forgings can also be used for non-destructive testing such as fluorescence penetration, magnetic powder penetration, and X-ray after roughing. Ultrasonic testing is divided into two types: comprehensive inspection and partial inspection. Partition inspection is a standard attempt to adopt differential sensitivity levels on different parts of the forging. The division of the area shall be in accordance with the requirements of the part drawings and shall be responsive in the forging drawings.
