Fe-Cr-C hardface alloys, the total volume fraction of (Cr,Fe)7C3 carbides was increased and the volume fraction of total austenite was decreased. Fig.2 shows potentiodynamic polarization curves of hardfacing alloys with different volume fraction of (Cr,Fe)7C3 carbides in 3.5wt% NaCl at 30°C.
THE EFFECT OF AUSTENITE VOLUME FRACTION ON THE DEFORMATION RESISTANCE OF 409 STAINLESS STEELS DURING HOT-STRIP ROLLING D. Chae, S. Lee, S. Son The mill log data obtained from the hot-strip rolling of 409 stainless steels were analyzed in order to investiga-te the effect of the chemical composition on the deformation resistance.
Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

Medium Charge Volume Fraction. The fraction of the mill volume occupied by the mill charge can be estimated based on a ratio of the cross-sectional areas. The cross-sectional area of the mill charge (A C) can be determined from: A↓C = H↓B / 6W (3H↓B↑2 + 4W↑2)
Mass fraction vs. mole fraction vs. volume fraction. Another problem of the parts-per notation is that it may refer to mass fraction, mole fraction or volume fraction. Since it is usually not stated which quantity is used, it is better to write the unit as kg/kg, mol/mol or m .
