- A single crystal Ni (in FCC) alloy bar is uniaxially pulled along [-123]. The bar starts to yield at σ =100MPa by slipping on (111)[-101] which hence is the most favorable slip system.why is it that glass fibers of different lengths have different strengthsIs it a good idea to coat or plate the surgical scissors with Cu-Ag alloy? Why or why not?
