Product Design AS/A Level - Heat Treatments for Metals

When a metal has been formed or shaped, the metal can sometimes require further treatments for its use, e.g. to relieve internal stresses in the metal. These are very specific, and are very useful as can be asked for in exams questions, and help to aid knowledge on metal manufacturing processes.
Here, an 8 slide PowerPoint lists the heat treatments most commonly used and listed in the AQA textbook, as well as handy video links to watch some of these processes, in order to really get to grips with understanding the processes.
Perfect for class lessons on heat treatments, or for personal learning/revision.
