Study Findings from B.Z. Sun et al Provide New Insights into Refractory Metals and Hard Materials (Microstructural studies of W-10 wt.% Cu composites prepared by using ultrafine composite powder)

By a News Reporter-Staff News Editor at Mining & Minerals -- New research on Refractory Metals and Hard Materials is the subject of a report. According to news reporting from Xiamen, People's Republic of China, by VerticalNews journalists, research stated, "Tungsten-copper (W-Cu) composites containing 10 wt.% Cu (W-10Cu) were prepared by pressing and sintering a type of ultrafine composite powder. Constituent phases, grain size and orientation relationship between Wand Cu grains were characterized and investigated."

The news correspondents obtained a quote from the research, "The results show that W-10Cu composites are composed of W and Cu elementary substance and orientation relationship between W and Cu grains is defined as [(11) over bar 4](cu)//[0(1) over bar 1](w) and (131)(cu)//(200)(w). The existence of the orientation relationship depends largely on the two factors. First, the grain sizes of both W and Cu were in the nanoscale range. Secondly, the interplanar spacing between both phases can match well owing to the residual stress of the W/Cu interface."

According to the news reporters, the research concluded: "Consequently, the obtained composites exhibited high density and excellent thermal conductivity."
