PRECIPITATION HARDENED FERROUS ALLOY WITH QUASICRYSTALLINE PRECIPITATES

摘要

According to the invention a precipitation hardened metallic alloy is provided, in which the strengthening is based on the precipitation of particles and wherein the particles have a quasicrystalline structure, said structure being essentially maintained at aging times up to 1000 h and tempering treatments up to 650 DEG C, the strengthening involving an increase in tensile strength of at least 200 MPa.
