摘要：
Fe-7.2Ni-16.2Cr-7Ti-3B (wt-%) composition was melted and cast into strips producing an in-situ TiB2 reinforcement within a stainless-steel matrix. The composite was characterised for microstructure and nanoindentation hardness. The microstructure consisted of in-situ formed particles of TiB2 and fine eutectic of austenite-borides. Superhigh nanoindentation hardness of 47.2 GPa was measured on TiB2 particles with 590.2 GPa elastic modulus while these values for the matrix were 6.95 and 277 GPa respectively.
