The microstructure evolution and interface characteristics of a directionally solidified Ti-43Al-3Si (at.%) alloy in an alumina (Al2O3) crucible with new Y2O3 skull-aided technology were investigated. The Y2O3-skull that is in contact with the TiAl-melt is relatively stable, which results in a more controlled reaction between the skull and the melt than in the case of an Al2O3 crucible is used....

* Author for correspondence: Research Institute, Lunuwila, Sri Lanka. Email: [email protected] Abstract. Attempts were made to identify the most suitable method to transport/store mature zygotic embryos of coconut (for excision of plumules later on) for cryopreservation work. Three different conditions, embryos transported/stored in albumen (solid endosperm) cores, solidified agar [0.45 %( ...

Article history: Received: 21.01.2015. Received in revised form: 21.07.2015. Accepted:23.07.2015. In order to examine the impact of admixture amount on the heavy metal solidification/stabilization effect of Magnesium Potassium Phosphate cement (MKPC), industrial dusts, iron ore tailings and slag were added into Magnesium Potassium Phosphate containing 5g/kg of heavy metals at the ratios of 0, 5...

Many methods exist for the analysis and for the characterization of the phase transformations of the rapidly solidified alloys, which are also described in the literature [1 3]. frequently used methods are the scanning electron microscopy (sEM), transmission electron microscopy For the characterization of the phase transformations in the alloys during the heat treatment the various methods of t...

X-ray diffraction (XRD) technique was adopted to test the mineral composition of quicklime-solidified loess with different lime-adding rates at curing periods. Scanning electron microscopy (SEM) and nitrogen adsorption were used analyze microporous structure solidified loess. The unconfined compressive strength limit moisture content combined evolution mechanism microstructure change period cla...

Nano-solidified intermedias (NSI) of cisplatin were prepared via biomineralization and applied to reverse the drug resistance of cancers in vitro and in vivo by an alternative internalization pathway.

Fe-Ni alloys of meteoritic composition were solidified by a plane front solidification technique. Distribution coefficients of Ni, P, Ir, Ge, and Cu were determined from the composition data of the plane front solidified alloys. Equations that describe the distribution coefficients (P, Ni, Ir, Ge, and Cu) as a function of S and P content as well as S to P ratio were used to calculate solute par...

A novel microstructural architecture consisting of Cr23C6 carbide spatial columns was created in solid components of Co-26Cr-6Mo-0.2C fabricated from powder by additive manufacturing using electron beam melting. These columns of carbides extended in the build direction and are formed by the x-y rastering of the electron beam to pre-heat and melt powder layers using CAD models. These microstruct...

In order to provide technical information needed by the U.S. Nuclear Regulatory Commission to evaluate the adequacy of near-surface disposal of decontamination wastes, Brookhaven National Laboratory has measured the release of organic reagents from solidified simulated decontamination wastes. The waste streams consisted of either mixed-bed ion-exchange resins or anion exchange resins equilibrat...
