FER-4 was taken in the south pit from a cherty magnetite iron-formation .

FER-4 was taken in the south pit from a cherty magnetite iron-formation containing chloritic tuff. The mineral assemblage of FER-4 is similar to that of FER-3, but the proportions of the minerals differ.

FeR-3 and FeR-4: four Canadian iron-formation samples pre . Precise and accurate determination of ferrous iron mass fraction in silicate rocks and geological reference materials is still a significant challenge due to the labile nature of the analyte.

FeR-3 and FeR-4: four Canadian iron-formation samples pre-. pared for use as reference materials. Here, we report a modified and improved procedure for the determination of ferrous iron mass fraction, capable of yielding moderately accurate and highly precise results in a relatively shorter time than before. This modified technique requires a more convenient operational procedure than the classical method.

Four natural gypsum rock samples were prepared and certified for major elements and some trace elements by. .

Using the compiled analytical data for the constituents of four Canadian iron-formation reference samples, a comparison is made among nine different robust estimators of true value, including the median, median, Gastwirth median, trimean, quarter-trimmed and sixthtrimmed means and the three Hampel estimators.

The possibilities of Fe-Al intermetallic system production by vacuum sintering and .

The possibilities of Fe-Al intermetallic system production by vacuum sintering and impact consolidation of powder bodies, as well as the influence of the regimes of the methods used on the structure and properties of iron aluminides were studied in the article. 1 Institute for Problems of Materials Science, National Academy of Science of Ukraine.

The morphology and the conditions for formation of Fe3N are clarified; it forms only on the surface of {lll}α or near {lll}α grains and grows in {112}α directions during nitriding treatment at temperatures between 450 and 550°C

The morphology and the conditions for formation of Fe3N are clarified; it forms only on the surface of {lll}α or near {lll}α grains and grows in {112}α directions during nitriding treatment at temperatures between 450 and 550°C. Fe16N2 and Fe4N are also formed preferentially on the surfaces of {00l}α. and {210}α grains, respectively.
