Directional solidification experiments were carried out to estimate the effect of solidification velocity and temperature gradient on primary dendrite arm spacing (PDAS) in the Ni-based superalloy, CMSX-4 alloy. The specimens were solidified at velocities of 1, 5, 25, 50 and 100 mm/s under given temperature gradients of 12.5, 18, 23..... More
