| Q.C. Metallurgical Laboratory Inc. has extensive experience in
the science of metallography. Our staff can conduct macroscopic and
microscopic examinations of all metals, alloys, cast materials, forgings
and welds. Samples can be analyzed with our digital stereoscopes
or by a scanning electron microscope. QCML routinely performs the
metallography tests listed below and is A2LA accredited for those
procedures. |
