Understanding Annealing: Reversing Cold Work In Dental Alloys
Understanding Annealing: Reversing Cold Work In Dental Alloys Write a short note on annealing. Answer: The effect associated with cold working (for example, Strain, Hardening) can be reversed by simple heating of the metal. The process is called annealing. The more severe the cold working the more readily annealing occurs. Annealing is generally comprised of three stages … [Read more...] about Understanding Annealing: Reversing Cold Work In Dental Alloys
