WebJan 16, 2024 · A systematic study of the interactions among structural, compositional, and coherent strain evolutions during GB precipitation is the key to revealing the microscopic mechanisms related to the effect of lattice misfits. Atomic-scale studies of GB precipitation can provide the most direct picture of such evolution. WebThe growth of heteroepitaxially strained semiconductors at the nanoscale enables tailoring of material properties for enhanced device performance. For core/shell nanowires (NWs), theoretical predictions of the coherency limits and the implications they carry remain uncertain without proper identification of the mechanisms by which strains relax.

WebJul 3, 2024 · By fitting the calculated Δ Gf /N versus 2 A/N data into the linear relation in Eq. ( 2 ), one can deduce the coherent strain energy (Δ GCS) and interface energy ( γ) from the intercept and slope, respectively. This procedure was performed for Al 3 Er (L1 2 )/Al 3 Sc (L1 2) with the three different contacting facets as shown in Fig. 2. WebWhere, G denotes the modulus of rigidity; ε is the coherent strain; f is precipitate volume fraction; r is precipitate radius; and b is the Burgers vector. The degree of precipitation strengthening in Equa-tion (1) above is proportional not only to the precipitate size and volume fraction, but also to the coherent strain to the power of 3/2.
