Forging low times the organization defects (1) large grain: if the beginning of the forging temperature is too high and the degree of deformation is not enough, or the end of the forging temperature is too high, or the end of the forging deformation falls into the critical deformation zone may be in the steel forging low times the organization of coarse grain defects. Aluminum alloy deformation degree is too large, the formation of weaving; high temperature alloy deformation temperature is too low, the formation of mixed deformation organization can form coarse grain. Coarse grain make...
Forging and forging have their own advantages and disadvantages, decide which process is better quality depends on the specific production situation and requirements. First, the basic concept of forging and forging Forging refers to the use of a variety of forging machinery to deform and process metal materials manufacturing process. Among them, forging is the use of high-pressure forging machine will be heated metal materials pressed into the desired shape, forging is to hammer the metal...
