WebJan 24, 2024 · According to the equivalent strains corresponding to positions 1, 2, and 4, as listed in table 1, it was concluded that the twin volume fraction decreased with increasing strain scale. It is known that the twin content decreased with increasing the strain scale during the detwinning process [41, 42]. WebVolume fraction. In chemistry and fluid mechanics, the volume fraction φ i is defined as the volume of a constituent Vi divided by the volume of all constituents of the mixture V prior to mixing: [1] Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18. It is the same concept as volume percent (vol%) except that the ...
