Imperfections In Metals:

The discussion of sequence in microstructures in the earlier lesson supposed idealized microstructures. In fact, materials are not composed of perfect crystals, nor are they free of impurities which alter their properties. Even amorphous solids have imperfections and impurities which change their structure.

IDENTIFY the three categories of microscopic imperfections found within crystalline structures.

STATE how slip occurs within crystals.

IDENTIFY the four categories of bulk defects.
