  The analysis model of the number of fatigue cycles required for the fatigue crack in the vicinity of the defect can be divided into the following two groups:

  1) The voids or deodorized inclusions are treated as gaps, and in the analysis of these defects stainless steel tee strength is based on the estimated fatigue limit.

  2)Stainless steel tee matrix dislocation at the inclusions at the inclusions is caused by inclusions cracking or interface deodorization reasons. In the inclusions cracking or interface deodorization at the same time, in the matrix began to form fatigue cracks. In a group of models of stainless steel tee fatigue cracks from the intermolecular particles began to nucleate the model, Chang, Morris and Buck to crack nucleation process as a dislocation plug process. Crack initiation consists of two successive events: brittle particles are cracked and cracked from stainless steel tee into the ductile matrix.

  The particle will crack when the elastic strain of the particle near the dislocations reaches the critical value. When the total energy of the system reaches its minimum, stainless steel tee will develop in the matrix. The total energy consists of four components: the elastic strain energy caused by the stress field in the dislocation of the stranger, the effective surface energy required for the crack propagation, the work that must be done to open the external stress of the crack, and the elasticity of the crack under the applied stress field Strain energy.
