In this study we report on the core structure of <c+a> dislocations on Pyramidal I planes and some interesting slip features, including: 1) a newly identified mechanism for the transition from pyramidal I slip to pyramidal II slip through cross-slip of screw-segments or by cooperative slip of edge-segments on two equal and alternative pyramidal I planes and 2) climb of both pyramidal I and pyramidal II <c + a> dislocations at low temperatures.
