Abstract

Effects of different ratios of Ni to Al on the ductility and toughness of Ni_33+xAl_28-xCr₃₀Mo₄Nb₅ (x=0, 6, 9, 12) alloys are investigated. High temperature compression test is also conducted. The results show that with ratio of Ni to Al up to 1.77, γ phase precipitation result in ductility and fracture toughness enhanced at room temperature. The reinforced Cr₂Nb-type phase and γ phase benefit for the high temperature strength and room temperature ductility, respectively.
