WebbAngular acceleration α is defined as the rate of change of angular velocity. In equation form, angular acceleration is expressed as follows: α = Δ ω Δ t, 10.4. where Δ ω is the change in angular velocity and Δ t is the change in time. The units of angular acceleration are rad/s /s, or rad/s 2. If ω increases, then α is positive. WebbThe effect can be rationalized with respect to the particle dispersion level where is the volume fraction of the second phase and r is the radius. At low the grain size is determined by the number of nuclei, and so initially may be very small.
