Data on Materials Science Reported by Researchers at Yanshan University (Micrometric grained Al synthesized via quasi-hydrostatic ultra-high pressure consolidation of micrometric Al powders)

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Materials Science is now available. According to news originating from Qinhuangdao, People's Republic of China, by VerticalNews correspondents, research stated, "This paper reports a study on the synthesis of a fully dense micrometric grained (i.e., grain size around 1 mu m) Al via consolidation of spherical micrometric-sized Al powders under a quasi-hydrostatic ultra-high pressure of 5 GPa."

Our news journalists obtained a quote from the research from Yanshan University, "Our result shows that during consolidation oxide films on powder surfaces can be effectively disrupted into nano-scale oxide particles, which promoted the formation of metallurgical bonding between powders and the retention of micrometric-sized grains. Consequently, the as-consolidated Al is characterized by micrometric grains (average grain size of 1.2 mu m) with a high density of nanoscale oxide particles (average size of similar to 25 nm) at grain boundaries."

According to the news editors, the research concluded: "The as-consolidated Al exhibits both high strength (ultimate tensile strength of similar to 130 MPa) and ductility (uniform elongation of similar to 10%)."
