Abstract

An in situ formed martensitic dendrite reinforced Fe-11Nb-10Ni-5Mn ultrafine composite was developed by copper mold casting. This new class of ultrafine composite composed of micrometer-scale martensitic α'-Fe dendrites and ultrafine-scale alternating eutectics exhibits a high fracture strength of 1.6. GPa and a large compressive plasticity up to 10.5%. These excellent mechanical properties originate from the precipitation of the martensitic α'-Fe dendrites containing numerous nanometer-scale laths which are effective to generate multiple shear banding and restrict the rapid propagation of localized shear bands.
