Microhardness and nodularity (Vickers)

One V-6 engine casting part is submitted to determine the nodularity and Vickers hardness of the material.

PURPOSE

Demonstrate the ability of Clemex CMT to perform and measure indentations. With the help of additional analysis modules, Clemex CMT is also capable to determine the nodularity of particle in the material. The technical report is linked at the bottom of this page (click the Download PDF link below).

RESULTS

The Vickers hardness measurements are performed on 10 fields.  The nodularity distribution across these fields is also analyzed. Automated statistics and graphs are generated and cumulated
