A356 is a primary aluminum
alloy with good ductility and fatigue properties at low to intermediate temperatures.

alloy with minor Ti, Zr, Ni additions," Materials and Design, vol.
In terms of grain size, although the recrystallization and grain growth occurred during solid-solution treatment, the grain size of the Cu0.9Hf alloy is lower than the
alloy with a lower Hf content.

alloy with small Cu content," Corrosion Science, vol.
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.
An
alloy with a 4% indium content results in a raw materials cost of $18.16 per pound before the metals are alloyed or fabricated to a form.
The superalloy material is a nickel-based
alloy with a composition including nominally mass fractions 60 % Ni, 5 % Cr, 10 % Go, and a number of additional alloying elements.
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.
It was expected that the
alloy with high nickel content would show better corrosion resistance due to the formation of thicker oxides on the surface of the alloy protects it from being easily corroded.
A comparison of this
alloy with as-cast A1-6%Si-0.5%Ba micrograph reveals two distinct features:
The M1 alloy (Mg
alloy with 1% Mn) is applied for castings that require low strength or welding [1-5].
The results indicated an Al-Cu-Sc
alloy with solution treatment at 590F retained its hardness, while the other alloys exhibited softening to varying degrees.
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.
* conventional 206
alloy with an addition of 30 ppm boron (B) as 5 Ti-1B master alloy;
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.
