Effects of infiltration parameters on mechanical and microstructural properties of tungsten wire reinforced Cu47Ti33Zr11Ni6Sn2Si1 metallic glass matrix composites

Preparation of W-Cu composites by infiltration of W skeletons – review

“…For example, in [23], Cu80-Zn20 alloy was infiltrated at 1100 °C into a W fiber preform with adequate density. For Cu-based metallic glasses, infiltration temperatures in the 850-900 °C range were found optimal forCu47Ti33Zr11Ni6Sn2Si1 [24] and around 965 °C for (Cu50Zr43Al7)99.5Si0.5 [25].…”

“…Still, in [3], infiltration at 1150 °C is reported with apparently fully dense structure. Lower temperatures are generally used with alloys having lower melting point than pure copper, such as Cu-Zn alloy [23] or Cu-based metallic glasses [24,25], or in combination with additional driving force for the infiltration, such as hot isostatic pressing(HIP) [26] or centrifugal force [3,27]. Besides the most common heating in a furnace, current heating (similar to spark plasma sintering) can be used; high current densities lead to markedly reduced processing times [30].…”
