Lever forging after trimming 2.1.1 Defects in analyzed Lever forging The macroscopic examinations of the lever forging showed numerous defects in the form of folds and cavity die underfills.Fig.2 show the forging with a marked underfill and Fig.3 show a place with a lap.[12] Fig. 2. Defects in lever forging: Underfill in lever forging ... WebFig. 1. Schematic view of the open die forging process. According to ASM Handbook [1] the main reason for performing the open die hot forging is to minimize defects originating from the casting process. Such defects are for instance segregations, inclusions, porosities due to gas entrapment or poor feeding, or coarse

Webvarious forging defects. Initially, some important forging terms that are widely used in this field are discussed. A brief description about classification of forging process on the basis of temperature of work piece (hot, cold, and warm forging) and on the basis of arrangement of dies (open, impression and closed-die forging) is given. Web4 de fev. de 2015 · Figure 3. Extrusion, radial forging, open-die forging (cogging) or rolling can produce a longitudinal grain flow. When sliced, this results in a grain flow that would be difficult to produce in a closed-die forging process. This would be ideal for a case with a longitudinal maximum principal stress in service.
WebOccasionally, internal defects are found in open die forgings. The potential origins of these internal fractures can be 1) unconsolidated solidification shrinkage voids, 2) heating or forging "bursts", or 3) hydrogen "flaking". Defect surfaces are often examined in a scanning electron microscope (SEM) to aid to determine their root cause.
