Research on the effect of liquid-liquid doping processes on the doped powders and microstructures of W–ZrO2(Y) alloys

Abstract

Highlights1. Three novel liquid-liquid doping technique for preparing precursors were proposed.2. Extremely homogeneous microspherical and flaky precursors were synthesized.3. Synthesis mechanism of three precursors were investigated in detail, respectively. 4. Reaction mechanisms for synthesizing cubic ZrO 2 in ternary liquid system were discussed.5. Novel method offers a general pathway in industrial production of high quality ODS-W powders.

Investigation of solution acidity influence on the morphological structure and physical and mechanical properties of particle-reinforced tungsten alloys

“…Tungsten and its alloys are largely employed in the defense and nuclear industry due to their high melting point, hardness and strength at various temperatures [1][2][3][4]. It possesses a high ductile-brittle transition temperature (DBTT) with a low recrystallization temperature, which negatively influences its physical behavior [5,6].…”
