Abstract
The invention discloses magnesium-gadolinium alloy which comprises the following components in mass percent: 6.58 to 10.50 percent of Gd, 0.001 to 0.005 percent of Sc, 0.01 to 0.025 percent of Ni, 0.01 to 0.015 percent of Cu, and Mg and inevitable impurities for the surplus. The magnesium-gadolinium alloy has the advantages that Gd element is added, the mechanical property of the alloy is improved by controlling the distribution and the existence form of Gd in alloy matrix, Sc element is added, a certain amount of Sc can obviously improve the creep resistance of the Mg-Gd alloy, the main reasons of improving the creep resistance are that a large amount of high-melting-point and stable MnSc phase is formed during the process of setting and the diffusion rate of Sc in Mg is very low, and the needlelike compound can effectively prevent dislocation glide.
Description
Technical field
The present invention relates to the alloy field, particularly relate to a kind of magnesium-gadpolinium alloy.
Background technology
Magnesium alloy is to add other elementary composition alloys take magnesium as base.Be characterized in: density little (about the 1.8g/cm3 magnesium alloy), specific tenacity is high, and Young's modulus is large, good heat dissipation, shock absorbing is good, and the loading capacity that withstands shocks is larger than aluminium alloy, and the corrosive nature of anti-organism and alkali is good.Main alloy element has aluminium, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium etc.What use was the widest at present is magnalium, secondly is magnesium-manganese alloy and magnesium zinc zirconium alloy.Be mainly used in the industrial sectors such as Aeronautics and Astronautics, transportation, chemical industry, rocket.Be the lightest metal in practical metal, the proportion of magnesium approximately is 2/3 of aluminium, is 1/4 of iron.It is the lightest metal in the practical metal, high strength, high rigidity.
DritsE was towards finding that adding heavy rare earth yttrium can produce Beneficial Effect to magnesium alloy in 1979, this important discovery make people develop a series of at high temperature have a good mechanical property contain the Y alloy, thereby be that the application of heavy rare earths (Heary rare earth, HRE) in heat resistance magnesium alloy laid a good foundation.Since the 9O age in 20th century, people satisfy the demand of national defence leading-edge field in order to obtain the more superior magnesium alloy of performance, begin to further investigate Mg-HRE alloy.Compare with light rare earths, heavy rare earth element mainly has following 2 advantages: the same solubility of (1) heavy rare earths in magnesium is large, and reduces sharply decline with solubility with temperature, thereby has well with molten reinforcement and precipitation strength effect; (2) heavy rare earths can be worked in coordination with the mechanical property of light rare earths or other transition element actings in conjunction raising magnesium alloy.
Thereby the alloy of magnesium and heavy rare earth element becomes the now emphasis of research.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of magnesium-gadpolinium alloy, and intensity is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of magnesium-gadpolinium alloy is provided, and the mass percentage content of its component is:
Gd 6.58%~10.50%；
Sc 0.001%~0.005%；
Ni 0.01%~0.025% ；
Cu 0.01%~0.015% ；
All the other are Mg and inevitable impurity.
In a kind of preferred embodiment of the present invention, the mass percentage content of described component is:
Gd 8.62% ；
Sc 0.002%；
Ni 0.01% ；
Cu 0.01% ；
All the other are Mg and inevitable impurity.
In a kind of preferred embodiment of the present invention, described magnesium-gadpolinium alloy also comprises the Nd of 1.65% ~ 2.28% mass percent.
In a kind of preferred embodiment of the present invention, described magnesium-gadpolinium alloy also comprises the Nd of 1.85% mass percent.
The invention has the beneficial effects as follows: magnesium-gadpolinium alloy of the present invention has the following advantages:
1), adds the Gd element: by distribution and the existence form of control Gd in alloy substrate, put forward heavy alloyed mechanical property.
2), add the Sc element: a small amount of Sc can obviously improve the creep-resistant property of Mg-Gd alloy, major cause is to have the stable Mn Sc of high-melting-point to form in a large number mutually in process of setting, and the rate of diffusion of Sc in Mg is very little, and the compound of this needle-like can effectively stop dislocation glide.
3), add the Nd element: can reduce the solid solubility of Gd, carry heavy alloyed aging hardening behavior, thereby improve the mechanical property of alloy, can improve the deformation processing performance of alloy.
