Interaction of Prismatic Dislocations and Intrinsic Faults

Abstract: Prismatic loops punched from voids in a quenched Cu+9.4 atyo Al alloy interact with intrinsic Frank loops to give stable unfaulted regions in the Frank loops bounded by Shockley partials. Two reactions involving dissociation of dislocations with b = 1/2 (110) are identified as nucleating the unfaulted regions. The stability of the unfaulted regions may be attributed to segregation of aluminium to the stacking fault or interaction between a Shockley partial and small defects.Prismatische Schleifen, die von Hohl… Show more

“…In this section, four numerical examples are carried out to validate the numerical model proposed in this work. We use the material properties of copper, the Young's modulus is E = 130 GPa, the Poisson's ratio is ν = 0.3, and the magnitude of the Burgers vector for all simulations is b 0 = 0.26 nm [31][32][33]. For the convenience of finite element implementation, normalized material properties are used in the simulation.…”
