  • Effects of Mechanical Vibration on Macrostructure and

    vibration on the grain size the casting defect distribution and mechanical properties. In comparison with the grains formed in the ascast state without vibration the grains in the inner area of a specimen became finer after mechanical vibration. The columnar structure remained in its outer region under all vibration frequency.

  • Defects Introduced into Metals During Fabrication and Service

    Defects may be produced during the processing fabrication and use of metals in service. Those that are introduced early in the processing chain may be carried forward to later stages where they can cause processing problems or initiate failure. Some of these defects result from complex metallurgical chemical and physical reactions that

    vibration the loose sands exerts strong impacts on the coating and the breakaway coatings will cause sand adhesion defect. Figure 7 shows sand adhesion defect at a vibration peak acceleration of 6.53g (0.45 mm 60 Hz). Fig. 7 Sand adhesions at 6.53 g The porosity of samples obtained under different peak acceleration is shown in Fig. 8.
