Stress And Strain: Definition & Diagram Stress: When a force acts on the body, tending to produce deformation, resistance is developed within the body to this external force. This internal resistance of the body to the external force is called “Stress”. Stress = "Importance Of Degassing In Preparing Direct Filling Gold" "Best Ways To Understand Compaction … [Read more...] about Stress And Strain: Definition & Diagram

Direct Filling Gold: Degassing, Compaction Methods, and Mechanical Condensation Techniques
Direct Filling Gold Degassing The heating process which removes the surface gases and ensures a clean surface is known as degassing or desorbing. Degassing removes the surface gases like oxygen, nitrogen, ammonia, moisture or sulfur dioxide which may be present due to improper storage. Direct filing gold may be heated by one of two methods as follows: … [Read more...] about Direct Filling Gold: Degassing, Compaction Methods, and Mechanical Condensation Techniques
Annealing and Degassing: Understanding Their Process, Benefits
Annealing Process: Understanding Its Benefits And Uses 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 occur. Annealing generally comprises of three stages. Recovery: In the recovery stage, the … [Read more...] about Annealing and Degassing: Understanding Their Process, Benefits
Direct Gold Restorations: Types, Properties, and Applications in Dentistry
Direct Gold Restorations Gold is malleable. A cast ingot of 15 mm thickness is beaten to the submicroscopic thickness of 15 to 25 µm. This is known as gold foil. Gold foils are made from pure metal by beating and rolling. Beating produces lightweight foils and rolling produces heavy-weight foils Fibrous gold is supplied in the form of sheets about 4 inches square which … [Read more...] about Direct Gold Restorations: Types, Properties, and Applications in Dentistry
