Stacking fault energy of face-centered cubic metals: thermodynamic andab initioapproaches

Stacking fault energy of face-centered cubic metals: thermodynamic and ab initio approaches.

The formation energy of the interface between face-centered cubic (fcc) and hexagonal close packed (hcp) structures is a key parameter in determining the stacking fault energy (SFE) of fcc metals and alloys using thermodynamic calculations. It is often assumed that the contribution of the planar fault energy to the SFE has the same order of magnitude as the bulk part, and thus the lack of preci...

Theory for plasticity of face-centered cubic metals.

The activation of plastic deformation mechanisms determines the mechanical behavior of crystalline materials. However, the complexity of plastic deformation and the lack of a unified theory of plasticity have seriously limited the exploration of the full capacity of metals. Current efforts to design high-strength structural materials in terms of stacking fault energy have not significantly redu...

A Thermodynamic Model for the Stacking- Fault Energy

ÐA general thermodynamic model for calculating the energy of stacking faults is presented and applied to f.c.c. Fe±Cr±Ni alloys. A distinction is made between ideal stacking faults and real stacking faults which are associated with an ideal stacking-fault energy (SFE) and an e€ective SFE, respectively. The ideal SFE is characterized by a chemical energy volume term and an interphase surface ene...
