A conformal Pt shell was deposited onto Ag NWs by a simple solution based method. The stability of Ag–Pt core–shell NW networks were systematically investigated. Highly stable utilized for the detection H 2 O .
The CoCrFeNi high entropy alloy (HEA) with face-centered cubic (FCC) crystal structure exhibits excellent ductility values even at cryogenic temperatures. However, since this HEA is relatively weak in strength, it may not meet the requirements of industrial applications terms strength-ductility trade-off. Therefore, systematic addition yttrium (Y) into was investigated present study to increase strength by solid solution and second phase strengthening. HEAs were produced vacuum arc melting,...
Abstract (CoFeNiMn) 100−x Cr x (x = 5, 20, 35 at.%) HEAs were produced using vacuum arc melting followed by suction casting industrial-grade raw materials and subsequent annealing at 1150 °C for 24 h. The increasing content triggered the formation of 7 C 3 in FCC matrix due to presence impurity materials. from 5 at.% raised hardness 206 (±7) 383 (±4) HV yield strength 210 350 MPa embedded phases matrix. HEA consists 20 was found be most promising alloy strength-ductility trade-off with...
