       Fracture test is a common method of macro inspection, which is an effective method to reflect the quality of material and heat. The source of the fracture fracture test can be divided into two kinds, one is in the process of using mechanical fracture or fracture tensile test, impact test, two fracture specimen according to the provisions of the special. The former is a very convenient method for the analysis of the macro structure and defects, which is a very convenient method for the analysis of the original surface. Fracture of special, you can check out defects in steel segregation, white spots, inclusions, these defects in thermal processing, deformation and pressure distribution along the direction of deformation, so it should be possible to select longitudinal fracture analysis. General steel diameter is greater than 40mm can produce longitudinal fracture, diameter less than 40mm steel sample production transverse fracture. Preparation method and test specimen, according to GB/T1814-1979 "steel fracture Inspection Law", this standard is suitable for structural steel, bearing steel, tool steel and spring steel hot rolling, forging, cold drawn steel and billet.
