Abstract
The present invention relates to a rapid solidification high-temperature aluminium-iron-cerium base alloy which is characterized in that the alloy contains 8 to 10 wt% of Al, 3 to 50 wt% of Fe, 7 to 1 wt% of Ce, 80 wt% of Ni, 5 to 1 wt% of Zr and 5 wt% of Zr as the rest. The alloy provided by the present invention has the advantages of higher high temperature strength and heat stability and larger increase than the aluminium-iron-cerium alloy.
Description
The present invention relates to ferroaluminium, particularly the high temperature aluminium iron cerium base alloy of rapid solidification.
The performance of advanced space vehicle depends primarily on low-density and high-strength and rigidity and resistant to elevated temperatures structured material.The better equivalent material of generally acknowledging is the Al-Li alloy at present, aluminum matrix composite and powder metallurgy 7000 and 2000 series, but when being higher than 150 ℃, the strength and stiffness of these precipitation hardenable alloy will obviously descend, for satisfying structured material needs 150～315 ℃ of uses, the Al-Fe-Ce alloy of dispersion strengthening type has obtained extensive exploitation, as the Al-8Fe-3.4Ce (CU78) of U.S. Alcoa company.Al-7Fe-6Ce (CZ42) etc., intensity is stretched in drawing during 315 ℃ of high temperature, σ
bReach 300MPa, σ
0.2Reach 280MPa, this alloy has very high solid solubility, can only obtain by the mode of with fixed attention fast or mechanical alloying.
The object of the present invention is to provide the more superior AlFeCe based high-temperature alloy of a kind of high-temperature behavior.
To the effect that of the present invention, a kind of quick solidifying high-temp aluminium iron cerium base alloy is provided, it is characterized in that: chemical ingredients is:
Fe???????Ce????Ni????????Zr???????Al
8-10 3-5 0.7-1.8 0.5-1.5 surplus
In the aluminium alloy provided by the present invention, the solid solubility of Fe and Ce is all very high, and near the maximum solid solution degree that can reach soon, these soluble solids are at compd A l between precipitating metal with fixed attention or in the processing subsequently soon with withing fixed attention
3Fe, Al, Fe, Al
3Even dispersion strengthening phases such as Ce, these disperse phases are the high-temperature stable phase, and higher high temperature strength is arranged simultaneously.The Ni that adds in the alloy, Zr then can form Ni
3Al and Zr
3Al High-Temperature Strengthening phase, thus the hot strength of alloy and thermostability are all increased.Be described in detail the present invention below by embodiment.
