        鍛件廠家找哪家
        詳細介紹:

        顯微組織


        ①鍛件大裁面處(檢驗非金屬同化、晶粒度)


        ②零件的高應力部位(檢驗同化、晶粒度、過熱)


        ③鍛件變形激烈、溫升嚴里處(檢驗過熱和晶粒度)


        ④鋁合金鍛件檢驗過熱、過燒,應在其小裁面并湊近其外貌部位取樣


        無損檢驗:


        對解放鍛件舉辦無損檢驗,要緊用超聲波探傷,有些鍛件也可在粗加工后用熒光滲透、磁粉深透、X—射線等無損檢驗法。超聲波檢驗分為全面檢驗和分區檢驗兩種。分區檢驗是在鍛件上的差別部位采取差別靈敏度等級的標準舉辦嘗試。區域的劃分應合乎零件圖樣的要求,并在鍛件圖樣中做出響應的規定。

        Microstructure


        1 Forging large cutting surface (testing non-metal assimilation, grain size)


        2 high stress parts of the part (test assimilation, grain size, overheating)


        3 Forgings are intensely deformed and the temperature rises to the extreme (testing overheat and grain size)


        4 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:


        For 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.
