Now, materials scientists have quietly taken aim at one common use of that harmful substance by creating a nontoxic alloy with
the potential to replace a coating containing chromium.
Their objective was to develop a model of creep strengths and other properties of particular alloys and examine the best results to design an alloy with optimal properties.
There's less work to melt the alloy with minimal pollution to the metalcasting facility and very little energy consumption.
Swigart said that research started in 1988, when Alcoa and Wright engineers were looking primarily for an alloy with
"corrosion resistance and no degradation in mechanical properties" that could replace aluminum alloys already used in aircraft.
The proxy statement and other documents filed by Alloy with
the SEC will be available free of charge at the SEC's website (www.
Even an alloy with
good fluidity, when overexposed to oxygen, may form a high surface tension oxide film that makes the fluidity die, "rounding off" of the leading edges as it flows.
Lehman Brothers has acted as financial advisor to Alloy with
respect to this transaction.
This oxide film acts as an insulator, preventing the wetting of the molten alloy with
the insert material.
Under the agreement, The New York Times Learning Network will provide Alloy with
daily content for the Gen Y audience from the "student connections" section of the Web site.
This technique was used later to produce nickel-aluminide, an ordered alloy with
excellent high-temperature properties.
New Alloy with
its LiveCD solution is a stand-out from the recent hybrid media noise.
D-5S austenitic iron fills the need for an alloy with
outstanding combinations of castability, machinability and useful mechanical and physical properties for thermal cycling conditions.
