| 20. | — | No evidence | Mild hot or cold working suggested by broken dendrites (BD) |
| 21. | As in 14 | As in 14 | — |
| 22. | Lead precipitation; distorted polygonal grains without twinning | Annealing below RT | Extensive parallel SLSTL and FG indicate heavy cold working causing permanent deformation |
