Abstract

Microstructural investigation on a series of (Fe65.8Ni 14.1B14.1Si6)100-xNbx alloys with x = 0, 2, 4, 6 and 8 reveals that Nb addition leads to modify the constitutive phase and morphology of ultrafine eutectic structure. The microstructural change from bimodal to irregular eutectic structures by addition of Nb has a strong influence to deteriorate the macroscopic plasticity. The bimodal structure and eutectic colony morphology is considered to be an important factor for enhancing both strength and plasticity.
