Description
Technical field
The present invention relates to a kind of NiAl-Cr (Mo) biphase eutectic crystal novel texture intermetallic compound of Zr modification, have NiAl phase, Cr (Mo) phase and Heusler (L2 in the described intermetallic compound
1-Ni
2AlZr) phase.
Background technology
At present, at power, petrochemical industry, transportation, particularly industrial circle such as aviation and space flight, be applied in structural metallic materials more than 600 ℃ and be generally Ni-based, iron-based and cobalt base superalloy.These materials have higher density (generally at 8.0g/cm
3More than), made member and weight of equipment are big, in order to alleviate structural weight, raise the efficiency, and reduce energy consumption, must develop the strong novel high-temperature alloy of low density, height ratio to adapt to the needs of related industries field future development.More urgent is is the superalloy of representative owing to be subjected to the restriction of fusing point with Ni base, Co base at present, near the ultimate temperature of its use.Even added three generations's superalloy monocrystalline of a large amount of precious metals, its use temperature also is no more than 1100 ℃.For satisfying the demand of gas turbine engine of new generation, being badly in need of exploitation, to hold warm ability be 1150 ℃ high-temperature structural material.
The fusing point of B2 structure long-range order NiAl is up to 1638 ℃, and is higher 300～350 ℃ than nickel base superalloy, and use temperature is expected to reach 1250 ℃; Its density 5.86g/cm
3Be 2/3 of nickel base superalloy only, the density after the alloying is 6.0g/cm
3About, thereby can improve specific tenacity effectively, reduce workpiece weight; The thermal conductivity of NiAl is big, and for general nickel base superalloy 4～8 times can make the thermograde of hot-end component reduce, thereby reduce thermal stresses, improve cold and hot fatigue property; In addition, NiAl also has excellent antioxidant property.But the normal temperature plasticity of NiAl is less than 1%, and fracture toughness property is
1000 ℃ of yield strengths of high temperature are less than 100MPa, serious restriction the utilization of its practicability.
The in-situ authigenic composite technology is one of effective way that solves material room temperature fragility and hot strength problem.By adding transition element, as Cr, Mo, V, W etc., can form pseudo-two component eutectic with NiAl is to utilize its endogenous refractory metal can make that mutually intensity improves, fracture toughness property increases.The synusia shape of eutectic structure is organized very tiny, and interlamellar spacing has only a few tenths of extremely several micron apart, and the mean free path of dislocation is very little, and the pinning between phase and phase causes the Hall-Petch type to be strengthened; In addition, the plasticity in the eutectic alloy and the NiAl fragility crackle in mutually can produce interaction, shows as the crackle bridge joint intuitively, and crack deflection and crack blunting make the toughness of NiAl pseudoeutectic alloy be improved.Fracture toughness property as NiAl-Cr (Mo) eutectic is 17～22MPam
1/2, its shock resistance also is better than AFN-12.But, the hot strength of NiAl-Cr (Mo) biphase eutectic crystal intermetallic compound is improved little, still can't satisfy the service requirements of gas turbine engine of new generation under 1150 ℃ of environment, carrying out further composition design and tissue design, is the effective way that improves NiAl intermetallic compound over-all properties.
