%X The effect of boron on carbide morphology of high Cr ledeburite steel has been studied. The results showed that B had obvious influence on eutectic carbide morphology in solidification structure and carbide granulation at high temperature. The addition of 0.02-0.05 wt pct B changed carbide morphology in solidification structure from strip eutectic and rosette eutectic into divorced eutectic. B accelerated carbide granulation through increasing unstability and lattice distortion of carbide and element diffusion. Granular carbide could be achieved when heated at 1150°C for 1.5 h.
