| Welding of cold-worked alloys anneals the heat-affected zone and eliminates the strength produced by cold working. |
|
| The heat of welding will anneal the copper in the heat-affected area adjacent to the weld and reduce the strength provided by cold working. |
|
| The grinding machine has no heat-affected zone, and operates without creating work hardening, a recast layer, or metallurgical damage. |
|
| The hardness of the heat-affected zone can be minimized by reducing penetration into the cast iron base metal. |
|
| Nitinol parts can exhibit heat-affected zones after thermocutting, crevices between grains, and sharp edges, which is why electropolishing nitinol parts is a necessary step. |
