Study of deformation stacking faults and dislocation microstructures in Cu–1Sn–Zn alloys

Generalised stacking fault energies of copper alloys - density functional theory calculations

“…Sn: A lot of effort has been made on TWA of Cu-Sn and Cu-Sn-based alloys [112,119,120,[136][137][138]. The negative value of SFE and TE in fcc Cu-Sn is the effect of the observed phase transition to D0 19 ordered structure in high Cu concentration alloys [137,138].…”

Mechanical alloying of Cu–xCr (x=3, 5 and 8wt.%) alloys

“…(3) [20], where K 1 1 1 ω 0 is 6.6 ± 0.1, G 1 1 1 is the shear modulus in the {1 1 1} fault plane, and a is the lattice parameter.…”

Simultaneous twinning nucleation mechanisms in an Fe–Mn–Si–Al twinning induced plasticity steel

“…110 2 a Another method is in the use of X-ray analyses following Schramm and Reed method [24], later modified by Dey et al [25], which considers the effect on dislocation parameters on SFE. It is trivial that both the TEM and X-ray methods have their own merits and demerits and should be used concurrently for reliability of the results.…”

“…The newer method of X-ray estimation of SFE [25] is based on the consideration of strain field anisotropy induced by the contrast factor of dislocations 28 and the effects of dislocation density and arrangement parameters on the SFs that supersede the original approach of Schramm and Reed [24]. Taking these effects into consideration, the expression for SFE is given as [25]: off radius of the dislocations, signifying the range over which the distribution of dislocations can be treated as random, is an anisotropy factor related to the X-ray A i elastic constants [27] and is the average contrast factor for the austenite (111)…”
