低倍组织：

①金属流线有要求处或能反映金属合理流向的断面上切取流线检验试样

②横向低倍试片尽大概取在大裁面处

③纵向低倍试片应取在零件的主轴线断面上

④用钢锭直接铸造成形的锻件，其低倍试片应在近目口一端处切取

低倍断口：

①在锻件易产生过热的部位切取试片

②在锻件变形里小的部位切取试片

③普通环境下，可在横向低倍试片上检验断口

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.
