Substitutional solid solution strengthening occurs when the solute atom is large enough that it can replace solvent atoms in their lattice positions. Some alloying elements are only soluble in small amounts, whereas some solvent and solute pairs form a solution over the whole range of binary compositions.
For this strengthening mechanism, solute atoms of one element are added to another, resulting in either substitutional or interstitial point defects in the crystal (see Figure on the right). The solute atoms cause lattice distortions that impede dislocation motion, increasing the yield stress of the material. Solute atoms have stress fields ...
For substitutional solid solutions, the Hume-Rothery rules are as follows: The atomic radius of the solute and solvent atoms must differ by no more than 15%: [1] % = % %. The crystal structures of solute and solvent must be similar.
In metal alloys with substitutional solute elements, such as aluminum-magnesium alloys, dynamic strain aging leads to negative strain rate sensitivity which causes instability in plastic flow. [4] The diffusion of solute elements around a dislocation can be modeled based on the energy required to move a solute atom across the slip plane of the ...
The IUPAC definition of a solid solution is a "solid in which components are compatible and form a unique phase". [3]The definition "crystal containing a second constituent which fits into and is distributed in the lattice of the host crystal" given in refs., [4] [5] is not general and, thus, is not recommended.
The two most prevalent shape-memory alloys are copper-aluminium-nickel and nickel-titanium (), but SMAs can also be created by alloying zinc, copper, gold and iron.Although iron-based and copper-based SMAs, such as Fe-Mn-Si, Cu-Zn-Al and Cu-Al-Ni, are commercially available and cheaper than NiTi, NiTi-based SMAs are preferable for most applications due to their stability and practicability [1 ...

Davis's law is used in anatomy and physiology to describe how soft tissue models along imposed demands. It is similar to Wolff's law, which applies to osseous tissue.It is a physiological principle stating that soft tissue heal according to the manner in which they are mechanically stressed.
