The purpose of the present work was to clarify the effects of parameters of porous ceramics on the characteristics of composites fabricated by high-pressure infiltration. Alumina with different porosity (15–70 vol%) and pore morphology was successfully fabricated by gelate-freezing and the partial-sintering, respectively. Alumina/aluminum composites were made by squeeze casting, the aluminum in...

Studies on the rheoforming of high melting point alloys are scarce due to difficulties in preparing semisolid slurries. This work applied a novel enclosed cooling slope channel (ECSC) prepare slurry and squeeze cast CuSn10P1 (weight percent) alloy. The microstructure phase formation slurry, properties liquid casting, rheo-squeeze casting with or without isothermal treatment were investigated th...

A comprehensive study on Sn macrosegregation behavior in ternary Al-Sn-Cu alloys was carried out by comparative analysis between gravity casting and squeeze samples. The microstructure distribution of the castings were characterized metallography, scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, a direct reading spectrometer. Results show that there are obvious di...

Aluminum is a non-ferrous metal and has the advantages of light specific gravity, corrosion resistance. can also be used in manufacture pistons, engine blocks, wheels, drums. Squezze casting process, where molten poured pressure applied until solidification process complete. Using hydraulic pressure, this technique able to improve physical mechanical properties, especially on aluminum base mate...
