Example: B4C fibres in AlSi, relief between fibres and
base material, Mag. 200 X.
Material from different phases is removed at different rates, due to
varying hardness or wear rate of the individual phases. Relif does
normally first occur during polishing. The most important parameters
to avoid relief are preparation time and polishing cloth. The preparation
time should be kept as short as possible. When developing a new method
the samples have to be checked in short intervals, 1-2 min. The polishing
cloths have a strong influence on the planeness of the sample. Polishing
cloth with low resilience produces samples with les relief than cloth
with high resilience.
