Metallography the study of microstructure has been invaluable tool to the progress of science and industry for the past three centuries.  The key to obtaining an accurate microstructure is having a properly prepared specimen that is truly representative of the material being examined. To insure achievement of such true surfaces it is important that each stage of sample preparation be carried out not only with accuracy, but also with understanding what each specific stage must accomplish. This month we will concentrate on Mounting Medias

a.       Compression Mounting

Compression Molding Techniques are used to produce hard mounts in a minimum of time.

The materials used are classified as:

1.       Thermosetting

2.       Thermoplastic

Thermosetting media requires heat & pressure during the molding cycle & can be ejected at minimum molding temperature.

Thermoplastic materials remain fluid at maximum molding temperature & become dense & transparent with a decrease in temperature & increase in pressure.

b.   Vacuum Impregnation

Many materials, both organic and inorganic may be porous and friable.  Vacuum impregnation with a suitable liquid Epoxy system  will produce a sample which is non-porous with excellent consolidation & rigidity.

All Metlab Corp’s, mounting medias have been scientifically formulated to achieve the best mounting properties in the shortness amount of time.  We strongly invite you to try our mounting supplies to achieve the best Metallographic Properties and price combination.
