PURPOSE:To improve the hardness and wear resistance by adding prescribed percentages of Si, Al, Ti, Co and secondary components such as one or more among V, Nb, Ta, Cr, Mo, W and a Pt group element to Fe. CONSTITUTION:The titled alloy consists of, by weight, 4-12% Si, 3-8% Al, 2-5% Ti, 1-5% Co, 0.1-6% in total of 0.1-5% one or more among V, Nb, Ta, Cr, Mo, W and a Pt group element and 0.01-1% one or more among Be, B, Zr, Y, Hf and a rare earth element as secondary components and the balance Fe. The alloy has superior hardness and wear resistance. |
