Abstract (en)
[origin: US2017145547A1] Alloys, processes for preparing the alloys, and articles including the alloys are provided. The alloys can include, by weight, about 0% to about 8% nickel, about 1% to about 6% tungsten, about 1% to about 4% copper, about 0.1% to about 2% chromium, about 0.01% to about 1% vanadium, about 0.01% to about 0.5% carbon, about 0.01% to about 0.1% titanium, about 0.001% to about 0.01% boron, about 0% to about 1% silicon, and about 0% to about 0.1% calcium, the balance essentially iron and incidental elements and impurities.
