Gold based bulk metallic glass
WebGold-based bulk metallic glass alloys based on Au–Cu–Si are introduced. The alloys exhibit a gold content comparable to 18-karat gold. They show very low liquidus temperature, large supercooled liquid region, and good processibility. The maximum casting thickness exceeds 5 mm in the best glassformer. Au 49Ag 5.5Pd 2.3Cu 26.9Si

WebJul 13, 2011 · A family of ultrahigh strength Co-based bulk metallic glasses (BMGs) with critical diameters up to 2 mm is synthesized in Co 65– x Ta x B 35 (at.%, x = 5–10) alloys by copper mold casting. The improved glass-forming ability associated with near eutectic compositions is attributed to the appropriate addition of Ta. WebDec 19, 2024 · In this research, a new type of bulk hybrid composites containing different amounts of Fe-based metallic glass (FMG) and SiC particles were successfully produced. FMG and SiC particles with varying percentages of volume were mixed with pure Al matrix and integrated by spark plasma sintering (SPS) method.
WebNov 12, 2013 · Bulk metallic glass alloys with a G/K value of over 0·41–0·43 are brittle. For example, the Fe 50 Mn 10 Mo 14 Cr 4 C 16 B 6 BMG alloy with the G/K ratio of 0·423 has been shown to be brittle, when compared with the Zr-based BMG alloys. A recent mechanics-based model also predicts the importance of elastic constant ratio on the …
