A Novel Hydro-Thermal Synthesis of Nano-Structured Molybdenum-Iron Intermetallic Alloys at Relatively Low Temperatures

Autor: A. A. El-Geassy, K. S. Abdel Halim, Abdulaziz S. Alghamdi

Publikováno v: Materials; Volume 16; Issue 7; Pages: 2736

Nano-structured Mo/Fe intermetallics were synthesized from precursors that contained 72/28% and 30/70% molar ratios of Mo/Fe, which were given as precursors A and B, respectively. These precursors were prepared from the co-precipitation of aqueous ho
