| الوصف: | The recent introduction of high entropy alloys presents an exciting opportunity for novel material performance, offering extensive possibilities for tailoring material properties. Dislocation mechanisms in these alloys must be fully understood since they play an important role in defining mechanical properties, such as plasticity and strength. Analytical models based on solute strengthening theory are utilized to investigate dislocation motion in both body-centered (BCC) and face-centered cubic (FCC) high entropy alloys. The analyses reveal that the magnitude and spacing of energy barriers associated with edge dislocations in BCC high entropy alloys are consistent with the models. For FCC metals, a framework is provided for understanding solute strengthening contributions to twinning mechanisms. Beyond the selection of materials, the choice of fabrication methods also significantly influences the mechanical properties of components. Additive manufacturing of metals stands out as a promising fabrication ... |
