GRAIN AND CELL SIZE

This image analysis Application Package allows you to measure grain intercept, intercept counts, intersection counts, grain boundary length, and grain areas in accordance with ASTM E 112, ASTM E 930, and ASTM E 1382 methods, with validation using the Heyn method.

NO VISIBLE GRAIN BOUNDARIES

Martensitic steel where the structure appears after a heat treatment. This it can also be found in exotic non ferrous metals like NiTinol, a Shape Memory titanium/nickel alloy.

SOLID GRAINS WITH VARIOUS COLORS

Solid grains with various colors (hue) like cast aluminum after anodization and viewed with polarized ligth and a lambda plate. Other materials with color etching.

Medium-carbon ferrite/pearlite

In medium-carbon steel the pearlite intensity variation makes it difficult separate the pearlite from the ferrite. A special Clemex algorithm allows to distinguish these phases in a single step.

AUSTENITIC STEEL

Grain boundaries with etching stains can easily be detected. A special Clemex algorithm was developed to exclude the detected stains from the grain size measurements.

SOLID GRAINS WITH VARIOUS GREY LEVELS

Examples are aluminum alloy or pure titanium viewed in polarized light without a lambda plate.

LIGHT GRAINS WITH DARK OUTLINES

Similar to austenitic, ferritic or prior-austenitic grain structures.

INCOMPLETE GRAINS WITH DARK OUTLINES

Grains found in materials like steel quenched and tempered.

ELONGATED GRAINS WITH DARK OUTLINES

Elongated grains from cold rolled steel.
