High cycle fatigue data for an alloy at various alternating stresses, 𝜎a (see figure) is given below.
A specimen of this alloy is subjected to multiple stress cycles sequentially in the following order: (i) first 5000 cycles at σa = 400 MPa followed by (ii) 25000 cycles at σa = 300 MPa and finally (iii) at σa = 500 MPa. Assuming that Miner’s law is obeyed, the number of cycles to failure at the final applied stress of
500 MPa is .
Consider a tilt boundary of misorientation of 2o in an aluminium grain. The lattice parameter of aluminium is 0.143 nm. The spacing between the dislocations that form the tilt boundary is ______ nm (round off to 2 decimal places).
