EFFECT OF COOLING RATE ON THE RAPIDLY SOLIDIFIED MORPHOLOGY OF MC CARBIDE OF A LASERGLAZED SINGLE-CRYSTAL NI-BASE SUPERALLOY

Abstract

Abstract: The effect of cooling rate on the growth morphology of MC carbide of a laserglazed single crystal Ni-base superalloy was comprehensively studied. The growth morphology of the rapidly solidified MC carbide was found in various very special radially arranged colonies which vary considerably with the solidification cooling rate and solidifying font shapes. The effect of cooling rate on the growth morphology is actually its direct influence on the solute-enriched liquid.

Key words: Carbide, Solidification, Superalloy
