Abstract
In or more aspects of the disclosure, aluminum alloys are presented. In one aspect of the disclosure an aluminum alloy may contain from 5 to 12 wt. % cerium, from 0.1 to 1.0 wt. % iron, and a balance aluminum. The aluminum alloy may further contain from 0.01 to 0.1 wt. % titanium. The yield strength of the aluminum alloy at 150° C. may range from 62 to 80 MPa. The elongation of the aluminum alloy at 150° C. may range from 10 to 26%.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . An aluminum alloy comprising:
from 5 to 12 wt. % cerium; from 0.1 to 1.0 wt. % iron; and a balance aluminum.
2 . The aluminum alloy of claim 1 further comprising from 0.01 to 0.1 wt. % titanium.
3 . The aluminum alloy of claim 1 , wherein yield strength at 150° C. ranges from 62 to 80 MPa.
4 . The aluminum alloy of claim 1 , wherein elongation at 150° C. ranges from 10 to 26%.
5 . The aluminum alloy of claim 1 , wherein there is 10 wt. % cerium, 0.1 wt. % iron, and the balance is aluminum.
6 . The aluminum alloy of claim 1 , wherein there is 7.5 wt. % cerium, 0.2 wt. % iron, and the balance is aluminum.
7 . The aluminum alloy of claim 1 , wherein there is 4.5 wt. % cerium, 0.5 wt. % iron, and the balance is aluminum.
8 . A cast aluminum-based component comprising:
5 to 12 wt. % cerium, 0.1 to 1.0 wt. % iron, and a balance of aluminum.
9 . The cast aluminum-based component of claim 8 , wherein there is 10 wt. % cerium, 0.1 wt. % iron, and the balance is aluminum.
10 . The cast aluminum-based component of claim 8 , wherein there is 7.5 wt. % cerium, 0.2 wt. % iron, and the balance is aluminum.
11 . The cast aluminum-based component of claim 8 , wherein there is 4.5 wt. % cerium, 0.5 wt. % iron, and the balance is aluminum.
12 . The cast aluminum-based component of claim 8 further comprising from 0.01 to 0.1 wt. % titanium.
13 . The cast aluminum-based component of claim 8 , wherein yield strength at 150° C. ranges from 62 to 80 MPa.
14 . The cast aluminum-based component of claim 8 , wherein elongation at 150° C. ranges from 10 to 26%.
15 . A castable alloy comprising:
a ternary eutectic mixture of 5 to 12 wt. % cerium, 0.1 to 1.0 wt. % iron, 0.01 to 0.1 wt. % titanium, and a balance of aluminum.
16 . The cast-able alloy of claim 8 , wherein there is 10 wt. % cerium, 0.1 wt. % iron, and the balance is aluminum.
17 . The cast-able alloy of claim 8 , wherein there is 7.5 wt. % cerium, 0.2 wt. % iron, and the balance is aluminum.
18 . The cast-able alloy of claim 8 , wherein there is 4.5 wt. % cerium, 0.5 wt. % iron, and the balance is aluminum.
