        詳細介紹:

        低倍組織:


        ①金屬流線有要求處或能反映金屬合理流向的斷面上切取流線檢驗試樣


        ②橫向低倍試片盡大概取在大裁面處


        ③縱向低倍試片應取在零件的主軸線斷面上


        ④用鋼錠直接鑄造成形的鍛件,其低倍試片應在近目口一端處切取


        低倍斷口:


        ①在鍛件易產生過熱的部位切取試片


        ②在鍛件變形里小的部位切取試片


        ③普通環境下,可在橫向低倍試片上檢驗斷口

        Low magnification organization:


        1 metal flow line has a requirement or can reflect the reasonable flow direction of the metal


        2 horizontal low-power test strips should be taken at the large cut surface


        3 longitudinal low-power test strips should be taken on the main axis section of the part


        4 Forgings directly cast from steel ingots, the low-magnification test piece should be cut at one end of the near mouth


        Low-fold fracture:


        1 Cut the test piece in the part where the forging is prone to overheating


        2 Cut the test piece in a small part of the deformation of the forging


        3 Under normal circumstances, the fracture can be tested on the lateral low-power test piece.
