The effect of grain size on the fatigue strength is predominant in material with high stacking fault energy while the effect of grain size is negligible in low stacking fault energy material.
The material with low stacking fault energy is prone to sub-grain formation compared to the metal with high stacking fault energy.
The material with higher stacking fault energy has higher fatigue strength whereas the material with lower stacking fault will have a lower fatigue limit.
S1: Some old people are oppressed by the fear of death.
P: An individual human existence should be like a river-small at first, narrowly contained within its banks, and rushing passionately past boulders and over waterfalls.
Q: In the young there is a justification for this feeling.
R: Young men who have reason to fear that they will be killed in battle may justifiably feel bitter in the thought that they have been cheated of the best thing that life has to offer.
S: But in the old man who has known human joys and sorrows, the fear of death is somewhat object and ignoble, and the best way to overcome it is to make your interests gradually wider and more impersonal.
S6: Gradually the river grows wider, the banks recede, the waters flow more quietly, and in the end, without any visible break, they become merged in the sea and painlessly lose their individual being.

The Proper sequence should be:
The _______ the stacking-fault energy, the higher the separation between the partial dislocations and the ________ the stacking fault.
Three – phase to ground fault takes place at locations F1 and F2 in the system shown in the figure If the fault takes place at location F1, then the voltage and the current at bus A are VF1 and IF1 respectively. If the fault takes place at location F2, then the voltage and the current at bus A are VF2 and IF2 respectively. The correct statement about voltages and currents during faults at F1 and F2 is
