Metal Average Grain Size Evaluation

Purposes:

Unit area grain size and grain number is related to the size of the grains. The size of the grains has a decisive effect on the mechanical properties of tensile strength of the metal, toughness, ductility etc. Checking the material grain size can evaluate material properties.

Applications:

Steel, copper alloy, aluminum alloy, magnesium alloy, nickel alloy, titanium alloy etc.
