  cyclic saturation
For low strain amplitude, cyclic saturation occurred after an initial cyclic hardening stage, but for high strain amplitude, saturation could not be reached.
      
The initial hardening observed in base metal has been attributed to interaction between dislocations and solute atoms/complexes and cyclic saturation to saturation in the number density of slip bands.
      
However, the cyclic saturation stress of the bicrystal RB increased with strain amplitude and did not show a plateau in its CSSC.
      
At the same total cyclic strain amplitude, the cyclic saturation stress amplitude among the four alloys was highest in the alloy with 60 ppm B and lowest in the alloy with 29 ppm B.
      
Dense concrete made with low water-to-cement ratios develops a cyclic saturation curve.

The dislocation microstructure and, in particular, the formation of persistent slipbands(PSBs)as well as their characteristics of in the cyclic deformation of Ni polycrystal were studied by transmission electron microscopy (TEM).The crystallographic orientation of grains observed and PSBs were determined by the selected area diffraction pattern.The experimental results showed that near the starting point of cyclic saturation stage (N=1800) was found a ladder_like pattern similar to PSB in copper, which suggested that the end of the cyclic hardening stage corresponded largely to the nucleation of PSB.The PSB structure in the fatigued Ni polycrystal was a bulk phenomenon.The grain boundaries of the polycrystal were effective obstacles for PSB propagation and twin helped to nucleate the PSB.The PSBs terminated On grain boundaries or tapered away after they formed porpagated in the grain.ln addition to parallel PSBs on the primary slip system, PSB on the secondary slip system could also be seen in some grains favourably orientated for multiple slip.The dislocation microstructure and the formation and evolution of PSBs in the interior of fatigued Ni polycrystal were in agreement with the results osberved in fatigued Cu polycrystal

The symmetrical push-pull fatigue tests in load control were carriedout for prestrained polycrystalline Cu. The change in mechanical behaviour duringcycling was recorded in detail and the effect of various degree of prestraining onsaturated behaviour and dislocation structure was compared. The results show thatthe cyclic saturation state is still history-dependent at low stress amplitude and thedislocation structure after fatigue has "inheritance". The amount of softening hasbeen calculated at various load amplitudes and a softening threshold to be about0.43 to 0.45 of the flow stress, which is the same as low carbon steel, is obtainedby extrapolating method. Three stages cyclic process and their mechanism have beendescribed.

对预变形多晶Cu,在不同载荷下进行拉压对称的恒应力循环试验,比较了不同预变形对其饱和行为及位错组态的影响。结果表明,低应力幅下循环饱和行为仍与历史相关,疲劳后的位错组态具有“继承”性。计算不同载荷下的软化量并外推出疲劳软化门槛,约为流变应力的0.43—0.45左右,其值与低碳钢的几乎相同。本文还描述了循环过程的三个阶段,并对其机理进行了探讨。
