It would not be possible to produce an alloy of Al-Ta, because of the difference in melting points of Al (933 K) and Ta (3293 K) by any conventional process. However, it can be fabricated by mechanical alloying using ball …
Mechanical alloying (MA) is a solid-state powder processing technique that was originally developed a little over 50 years ago by John Benjamin of INCO. The intent was to produce a material that has adequate strength both at intermediate and elevated temperatures. See more Oxide dispersion-strengthened (ODS) alloys contain a solid-solution-strengthened matrix in which an oxide phase is uniformly dispersed. The amount of the oxide added is usually about 0.25–1.0 wt%. The … See more Since the first synthesis of an Au–Si metallic glass in 1960 by rapidly solidifying the melt at solidification rates of about 106K/s, a very large … See more In recent years, there have been investigations to synthesize nanostructured steels including plain carbon steels and stainless steels by different methods.
