   Tempering (Toughening)
   Tempering is the subsequent reheating of the hardened object to a lower temperature ($200^\circ \text{C}$ to $500^\circ \text{C}$) to relieve internal stress and increase ductility. This process is often judged by the oxidation color's that bloom across the metal surface. The color progression (pale straw $\rightarrow$ brown $\rightarrow$ purple $\rightarrow$ blue) corresponds to precis…

2. Heterogeneity

   Linked via "ductility"

   Grain Boundary Variations
   Within polycrystalline materials, grain boundaries represent regions of high heterogeneity due to differing crystallographic orientations. The statistical distribution of these orientations dictates properties such as ductility. For example, in high-entropy alloys, the intentional introduction of disparate atomic radii creates deliber…

   | Crystalline Bismuth Alloys | $50 - 150$ | $2.50$ | Low-Frequency Acoustic Dampers |
   The choice of design safety factor is directly linked to the material's perceived ductility and the consequences of accidental yielding. Materials exhibiting pronounced yield point behavior (like steel) allow for lower factors than those that transition gradually (like high-strength aluminum), as the unforeseen elastic rebound…
