Among all OMRP treatments, biggest change range appears in IMRP12 followed by IMRP10 and IMRP13.There was positive correlation between change range and increasing rate of available phosphorus. There was positive correlation between increasing rate of available phosphorus and decreasing amplitude of XRD argentite's main peak value.

The prior cycles with higher axial stress and larger strain range greatly restrains ratchetting strain of subsequent cycling with lower ones. Creep behavior plays an important role in the ratchetting strain and its influence on ratchetting behavior can not be neglected. Fracture morphology characteristics of two kinds of materials were investigated by scanning electron microscope. It shows that failure of material A is induced by cavitation and that of material B is induced by decohesion. For material A, with the decreasing strain amplitude the fracture surface shows more larger diameter globular particles under uniaxial loading and can be seen more obvious and deep crack under multiaxial loading. However for material B, with the decreasing strain amplitude fracture surface shows larger and larger scalelike shape and becomes more smooth under uniaxial loading, but fracture surface under multiaxial loading looks like more smooth than that of uniaxial loading, and shows gradually wave-like morphology.
