The poisoning effects that several ppm of P or Sb have on Na or Sr, during modification of hypoeutectic
During the solidification of hypoeutectic
gray cast iron, two main events can be differentiated, the precipitation of the primary phase and the eutectic phase.
4 ppm P for hypoeutectic
alloys, which is just within or below the commercial purity range of regular Al-Si cast alloys.
Melting layer has a very high hardness, the hardness can be above Hv1000, with the laser scanning speed increased and increased with metamorphosis hypoeutectic
white structure's refinement .
Corrosion behavior of hypoeutectic
Al-Cu alloys in H2SO4 and NaCl solutions.
This alloy relates to hypoeutectic
ones and consists of lamellae of [alpha]-phase, which occurred inside primary [beta]-grain.
The device fabrication process consists of a mesa recess etch for isolation, hypoeutectic
NiGeAu ohmic contacts and a 0.
Physical Characterization of the Permeability of Equiaxed Eutectic Structures in Hypoeutectic
Aluminum Alloys (E.
Strontium modification of hypoeutectic
aluminum alloys is suppressed by a small concentration of phosphorus.
This paper evaluates the dimensional stability (diameter, roundness and cylindricity) and surface roughness of reamed cylindrical holes using K10 cemented carbide welded blade reamers on aluminum-silicon hypoeutectic
(SAE 322) cast alloy at various cutting conditions in order to optimize the cutting process.
It was realized that, to have the thixoforming process of these hypoeutectic
alloys correctly applied, it is necessary to achieve a temperature where AlFCC coexists with the liquid rich-silicon; nevertheless, the semisolid behaviour will depend on the remaining solid's morphology and shape.
cast Al-Si alloys are highly susceptible to occurrence of the sharp edges of the coarse acicular silicon phase that promote crack initiation, and propagation in alloys and also the porosity formation
