Aluminum Specimen Metallographic Preparation
Specimen Preparation (Class 1 Procedures)
 |
DESCRIPTION
Aluminum and its alloys are relatively soft materials which have a wide range of alloy applications.
PREPARATION CHALLENGE
The difficulty in preparing these materials arises from the fact that these materials have oxide inclusions in the microstructure. Proper specimen preparation retains these oxides and thus eliminates scratching and smearing from these particles. If the specimen is not prepared properly, the microstructure will not be accurately represented.
