Plastic deformation mechanisms have been investigated in the MAX phase Ti2AlN. Nanoindentation has used to induce plastic a single grain, and Transmission Electron Microscopy (TEM) lamella extracted cross section through indent by using Focused Ion Beam (FIB) technique. By combining TEM observations automated crystal orientation mapping (ACOM), highly misoriented domains (HMD) revealed below na...

We compare the smooth and deformation equivalence of actions of finite groups on K3-surfaces by holomorphic and anti-holomorphic transformations. We prove that the number of deformation classes is finite and, in a number of cases, establish the expected coincidence of the two equivalence relations. More precisely, in these cases we show that an action is determined by the induced action in the ...
