Formation and Mechanical Properties of Cu–Zr–Al–Sn Bulk Metallic Glasses

Abstract

Formation and mechanical properties of Cu-Zr-Al-Sn bulk metallic glasses were investigated. The glass-forming ability of Cu 50 Zr 50 alloy is significantly improved with addition of Al, and the critical diameter for glass formation increases from 2 to 7 mm for

On thermophysical and mechanical properties of glass-forming alloys

“…3 and 4 for the Young's modulus, E, and the hardness, H v , respectively. The data have been collected from various sources [3,[12][13][14][15][16][17][18][19][20][21][22][23][24]. They encompass practically all known metallic glasses obtained both in ribbon and bulk form.…”

Effect of Si addition on glass-forming ability and mechanical properties of Cu–Zr–Al bulk metallic glass

“…Recently, much attention has been paid to the Cu-Zr-based metallic glasses [7][8][9][10], due to their simple composition, innocuous and free of noble elements, large GFA, and wide composition range. Research has demonstrated that element addition and displacing is an efficient way to prepare BMG with better GFA [3,[10][11][12][13][14][15]. The ternary Cu-based BMGs were first reported in Cu-Zr-Ti and Cu-Zr-Al alloy systems by Inoue group [8,16].…”

Effects of rare-earth elements on the glass-forming ability and mechanical properties of Cu46Zr47−x Al7M x (M = Ce, Pr, Tb, and Gd) bulk metallic glasses

“…Bulk Cu 50 Zr 42 Al 8 amorphous samples with 4-4.5 mm in diameter were successfully prepared by copper mold suck casting [4][5]. The GFA and properties of Cu-Zr-Al amorphous alloys can be enhanced by substituting Y [6][7], Nb [8][9][10][11], Ag [12][13], Be [13], Er [14], Sm [14], Sn [15], Gd [16][17], La [17], Ce [17], and Nd [17] for Zr. More excellent effect about rare-earth elements on the GFA and properties of bulk Cu-Zr-Al amorphous alloys and wide application in the industrial casting process can be expected.…”
