Fabrication of porous pure magnesium by MgH<sub>2</sub> produced by mechanical milling and spark plasma sintering (MM-SPS) process

نویسندگان

چکیده

Pure magnesium (Mg) powders with stearic acid added as process control agent (PCA) were mechanically milled (MMed) using a vibration ball mill. The MMed consolidated into bulk materials by the spark plasma sintering (SPS). Changes in hardness, thickness and solid-state reactions of SPS have been examined hardness measurements, vernier caliper an X-ray diffraction (XRD), respectively. Vickers material decreased increasing temperature. Minimum value was 17 HV. increased However, little effect time on observed. In materials, formation MgH2 solid phase reaction observed during sintering. During sintering, decomposed to produce hydrogen gas; it contributed expand materials. Porous pure could be formed only MM-SPS without addition foaming aid.

Fabrication of Nanostructured Cu matrix Nanocomposites by High Energy Mechanical Milling and Spark Plasma Sintering

Spark plasma sintering (SPS) is a sintering process that is capable of sintering hard worked powders in short times. This technique was used to fabricate bulk Cu and Cu-SiC nanocomposites. Pure Cu and mixed powders of Cu including 4 vol% of SiC nanoparticles were mechanically alloyed for 25 h and sintered at 750˚C under vacuum condition by SPS method. Microstructures of the materials were chara...

In-situ Fabrication of Transparent Magnesium Aluminate Spinel by Spark Plasma Sintering

Transparent polycrystalline spinel ceramic was fabricated without any sintering aids by spark plasma sintering method of a mixture of Al2O3 and MgO powders for only 10min soak at 1250°C. Densification, microstructure and optical transparency of spinel were examined. The spinel exhibits an in-line transmission of 55% for a visible-wavelength of 470nm and high hardness value of 2040 HV.
