Supersolidus liquid-phase sintering of ultrahigh-boron high-carbon steels for wear-protection applications

► Fe-C-B steels can be fully densified by SLPS and HIP. ► HIP-temperature is limited due to a low-melting eutectic in the ternary Fe-C-B system. ► SLPS processing produced specimens with a density close to the bulk value. ► Liquid phase of 30-50 vol.% was required to reach fully compacted specimens. ► Specimens in the SLPS state had a higher wear resistance than HIP-densified specimens.
