ZR ALLOYING EFFECTS ON THE MICROSTRUCTURE, COMPRESSION PERFORMANCE AND OXIDATION RESISTANCE OF REFRACTORY HIGH ENTROPY ALLOYS

Three refractory high entropy alloys (RHEAs) with nominal compositions of Mo _0.5 NbHf _0.25 CrZr _x TiAl (x = 0, 0.5, 1, mole ratio) were prepared by vacuum non-consumable arc melting technology.The influences of Zr addition on the microstructure, compressive performance and oxidation resistance at 1473 K of RHEAs were investigated and evaluated i

For energy-efficient resource management, void node avoidance is one of the key objectives in the energy constrained underwater wireless sensor networks (UWSNs).In this paper, we propose two new routing protocols for the UWSN which is one of the end parts of a cloud.The first protocol is avoiding void node with adaptive hop-by-hop vector based forw
