AbstractBy the control of composition, clustered atomic configuration and stability of the supercooled liquid in the rapid solidification and powder metallurgy processes, high-strength Al-based bulk alloys containing nanoscale nonperiodic phases were produced in AI-Ln-LTM, AI-ETM-LTM and Al-(V, Cr, Mn)-LTM (Ln=lanthanide metal, LTM=VII and VIII group metals, ETM=IV to VI group metals) alloys containing high Al contents of 92 to 95 at%. The nonperiodic phases are composed of amorphous or icosahedral (I) phase. In particular, the Al-based bulk alloys consisting of nanoscale I particles surrounded by Al phase exhibit much better mechanical properties as compared with commercial Al base alloys. The success of producing the Al-based alloys with good engineering properties by use of I phase is important for future development of I-based alloys as practical materials.

ABSTRACTCombining the reduction of the mineral oxide to a liquid metal and its rapid solidification provides an energetically favorable route tod provide metastable metallic particles or powders. Such an option is available with the Sustained Shockwave Plasma (SSP) reactor in which the mineral oxide is reduced using a carbon-based reductant within the plasma medium and subsequently rapidly solidified. This paper examines the degree of metastability of these metal particles using optical, electron and Auger microscopy and discusses the potential of this processing route.

Generally speaking, complex rapid solidification process kinetics can be solved by using numerical techniques only. In that sense, numerical methods for simulation of the solidification processes can be categorized as fixed-grid and interface tracking schemes, where the former ones cannot accurately track a sharp solid-liquid interface. Therefore, in this paper a numerical method based on control volume methodology and interface-tracking technique for computer simulation of rapid solidification accompanied by melt undercooling will be described and applied to analyze the solidification of a ceramic sample on a metallic substrate. A digital pyrometry system will be used for temperature measurement in an Arcimage furnace because of its merit of presenting data directly as temperature in real time with high accuracy. The characterization of solidification of a ceramic sample will be done by using the defined numerical method and inverse heat transfer analysis.
