Volume Fraction of Phase in Polycrystalline Material
Formula:Vv = (phaseArea / totalArea) * 100
Introduction to Volume Fraction Calculator
The volume fraction, often expressed as Vv, of a phase in a polycrystalline material is a ratio that represents the volume of a certain phase (or grain type) within the entire volume of the material. This is calculated from a two-dimensional micrograph by dividing the area occupied by the phase of interest by the total area examined, presuming a uniform distribution through the thickness. The result is expressed in percentage.
Parameter usage:
totalArea
= Total area examined in the samplephaseArea
= Area occupied by the phase of interest
Output:
volumeFraction
= Percentage volume fraction of the phase
Data validation
Total area must be greater than zero and phase area must be non-negative and less than or equal to the total area examined.
Summary
This calculator is used to determine the volume fraction of a specific phase within a polycrystalline material. It is a key metric in materials science for understanding the properties of multiphase materials.
