Section Summary

This section has discussed point defects, dislocations and experimental observations of the various dislocation configurations observed in ceramics. These imperfections are the basic features of each and every material, including 

It has also been briefly stated that some of the planar defects, such as low-angle grain boundaries and SFs may be interpreted as being related to specific dislocation configurations. 

This section began with point defects, which have either direct or indirect influence on the mechanical properties of materials, discussing point-defect hardening, climb, etc., but a later chapter will show that creep is greatly associated with the mobility of point defects. No discussion was included here on the important aspect of the physical properties of point defects, which is beyond the scope of this book.

Before a fan selection can be completed either by the owner s engineer or the manufacturer, a system resistance calculation must be made at several selected fan volume flow rates. This will be discussed in the section, Summary of Fan System Calculations, Figure 12-128...
