relative softness of the material, coupled with the highly polished
surface, allow for the creation of large (and thus easily visible)
indentations.
Figure3- 22Single-crystal Aluminum sample, indicated by marker 2
The theoretical modulus for single-crystal aluminum is 70.4 GPa. The
hardness should be on the order of 0.2 GPa. Note that single-crystal
aluminum exhibits passivation at its surface, and thus surface effects are
anticipated. Note also that significant pile-up is typical in single-crystal
aluminum.
The surface of the standard is shipped laboratory grade. The surface is
very smooth and free of debris, and it should be maintained in this
fashion. Note that cleaning the standard will corrupt it. To avoid this,
always use care in handling the disk when removing it from the sample
tray and then always place the plastic cap (provided with the puck) back
over the standard when it is not in use.
After extended use, your single-crystal aluminum sample may require
re-polishing. Through proper handling, you may reduce this occurrence,
but after extended service and many indentations, re-polishing will be
required. When the standard has reached the end of its serviceable life or
your standard has been damaged, a new standard may be purchased by
contacting your Agilent service representative.
