Solid solution strengthening can play a very important role in the performance of heat resistant steels, not only because of its substantial strengthening effect as such, but also because of the fact that the effect that solid solution strengthening is, by definition, time independent.
Strong solid solution strengthening by Cr was predicted.
It has been found that Mo plays a strong solid solution strengthening effect on this kind of HEAs.
High-entropy alloys (HEAs) are evolving multi-component intermetallic systems, wherein multiple principal elements tend to form single solid-solution-like phases with a strong tendency to solid solution strengthening.
The increased hardness of both Cu-Ti and Cu-Mo systems with increasing the solute contents are quantitatively explained by combining several strengthening mechanisms, including solid solution strengthening, grain/twin boundary (GB/TB) strengthening, solute segregation-induced strengthening.
The high strength was attributed to the dispersion strengthening, solid solution strengthening, sub-structure strengthening, and dislocation strengthening, in which sub-structure strengthening is dominate.
Contributions from the several mechanisms (boundary strengthening, solid solution strengthening, precipitate strengthening and dislocation strengthening) are discussed and estimated using simplified models.
Solid solution strengthening by the constitutive elements of the alloys was calculated using Labush approach.
The solubility of titanium and molybdenum in ferrite is low and is assumed to have negligible solid solution strengthening effect.
Mechanical properties of steels can be improved by work hardening, solid solution strengthening, grain refinement, and dispersion strengthening.
