4 important questions on Fabrication and Processing of Engineering Materials - Fabrication and Processing of Glasses and Glass-Ceramics
What five specific points are important in the processing of glasses?
2. The working point, viscosity is 103 Pa.s, glass is easily deformed.
3. The softening point, viscosity is 4 * 106 Pa.s, highest temperature it can be handled without deforming.
4. The annealing point, viscosity is 1012 Pa.s, residual stresses can be removed within 15 minutes.
5. The strain point, viscosity is 3 * 1013 Pa.s, fracture will occur before deformation.
What five different methods are there for glass forming?
- Blowing
- Drawing
- Sheet forming
- Fiber forming
What is thermal shock?
