中文摘要	Bulk Fe2B and Fe3B alloys have been prepared by a self-propagating high temperature synthesis combining rapid solidiﬁcation technique. The Fe2B and Fe3B alloys are composed of t-Fe2B dendrite and ultraﬁne eutectic matrix with t-Fe2B and -Fe, and the dendrites are rounded by the matrix. The volume fractions of the dendrite of the Fe2B and Fe3B alloys are 90% and 20%, respectively. The fracture strength reduces from 3400MPa to 2660MPa with the increase of dendrite content, but the strain at fracture rises markedly from 3% to 19%. The result indicates that a small quantity of dendrites embedded in the ultraﬁne eutectic matrix can reinforce the ductility.
