چکیده
High-entropy alloy AlCrFeCoNi powder with a metastable body centered cubic (bcc) structure is produced by inert gas atomization. This state largely preserved after processing the high-velocity-oxygen-fuel (HVOF) thermal spraying. A heat treatment conducted objective to form duplex comprising ductile face (fcc) phase. The formation of an additional fcc phase accompanied decrease in hardness and significant improvement wear resistance. alternative route, spark plasma sintering (SPS), causes bcc structure. Detailed analyses behavior for all production routes contribute better understanding microstructural effects high-entropy alloys.

متن کاملMicrostructure and Properties of Spark Plasma Sintered MoAlB Ceramics
Advisor: Bai Cui Molybdenum aluminum boride (MoAlB) is a ternary transition metal boride which has promising aeronautic and nuclear applications. It inheres excellent properties of the binary transitional metal borides (e.g., MoB, ZrB2) such as high melting temperature, high hardness, and thermal conductivity. Besides, MoAlB is superior to MoB because: (1) the Al element provides an oxidation r...
