Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
As a new article of manufacture, a cast metal component having improved tensile ductility within the temperature range of about 700° C. to about 800° l C., particularly about 760° C., said component being formed of an alloy consisting essentially of up to 10.5% chromium, from 4% to 12% in total of titanium plus aluminum, up to 20% cobalt, up to 25% tungsten, up to 10% molybdenum, up to 12% tantalum, up to 6% niobium, up to 5% iron, up to 3% vanadium, up to 1.5% zirconium, up to 0.5% carbon, up to 0.5% manganese, up to 0.3% silicon, up to 0.3% boron, and from 0.005% to 0.15% yttrium, the balance being essentially nickel.
Claim 2
Dependent Claim
114 words
As a new article of manufacture, a cast metal component having improved tensile ductility within the temperature range of about 700° C. to about 800° l C., particularly about 760° C., said component being formed of an alloy consisting essentially of up to 10.5% chromium, from 4% to 12% in total of titanium plus aluminum, up to 20% cobalt, up to 25% tungsten, up to 10% molybdenum, up to 12% tantalum, up to 6% niobium, up to 5% iron, up to 3% vanadium, up to 1.5% zirconium, up to 0.5% carbon, up to 0.5% manganese, up to 0.3% silicon, up to 0.3% boron, and from 0.005% to 0.15% yttrium, the balance being essentially nickel.
Claim 3
Dependent Claim
30 words

Claim 4
Dependent Claim
20 words
A cast metal component as set forth in claim 1 in which the aluminum content is from 5% to 7%.
Claim 5
Dependent Claim
108 words
As a new article of manufacture, a cast metal component having improved tensile ductility within the temperature range of about 700° C. to about 800° C., particularly about 760° C., said component being formed of an alloy consisting essentially of about 3% to about 10.1% chromium, up to 3.65% titanium, about 5.5% to 6.7% aluminum, up to about 15% cobalt, up to about 19% tungsten, up to about 8% tantalum, up to about 6.05% molybdenum, up to about 1.4% niobium, about 0.05% to about 0.35% zirconium, about 0.015% to 0.1% boron, about 0.08% to about 0.15% carbon, about 0.01% to about 0.085% yttrium, and the balance essentially nickel.
