25 Questions

1. The second level of the structure of materials - describing how the atoms are positioned in relation to one another as well and the type of bonding between them

2. An electron microscope that passes the electron beam through the sample and used the difference in the beam scattering and diffraction to view the object

3. Microscopes that focus a high- energy beam of electrons at the source and collect the back- scattered beam of these electrons

4. Materials in which the entire structure is a single unbroken grain

5. The edge lengths and angels of a unit cell; describes the sizes and shapes of the lattices

6. The lowest stress level at which a slip will begin in the material

7. The ares of a material that separate different crystallite regions

8. Correlation used to estimate the yield strength of a given material - based on grain size

9. Crystallite materials with sizes of nanometers in length

10. Large scale lattice defects that occur from alterations to the structure of the lattice itself

11. A point defect found in ceramic materials that occurs when a cation diffuses onto an interstitial site on the lattice

12. The clustering of atoms around an impurity that provide a template for crystal growth

13. A point defect that occurs in ceramics when both a cation and an anion are missing from a lattice

14. Point defects that result from the absence of an atom at a particular site

15. One of the bravais lattices that has one atom in each of the 8 corners of the unit cell and one atom on each face of the unit cell

16. A means of relating the amount of spreading in a X- ray diffractogram to the thickness of the crystallites in the sample

17. The systematic reduction in intensity of diffraction peaks from specific lattice planes

18. A specific set of h

19. A nullification caused by two waves interacting out of phase

20. The process of forming small aligned clusters of atoms that serve as the framework for crystal growth

21. The use of light to magnify objects up to 2000 times

22. The second step in the formation of crystallites - which is dependent on temperature and can be described using the arrhenius equation

23. A numerical quantity developed by the American Society for Testing and Materials (ASTM) to characterize grain sizes in materials

24. Composed of both the slip plane and the slip directions

25. The density a material would have if it consisted of a single perfect lattice
