    Notes: Abstract The properties and fundamental methods of preparing metallic beryllium are discussed on the basis of results obtained by Soviet authors. Comparison is made between thermal reduction of beryllium fluoride by magnesium, electrolytic extraction, and purification of beryllium by distillation in vacuum. Preparation of beryllium articles by different methods of powder metallurgy, melting in vacuum induction furnaces with centrifugal casting, extrusion of beryllium articles and the structure and properties of compact beryllium are discussed. It is found that the maximum tensile strength of pure beryllium samples extruded from a metal hot∞ pressed in vacuum is about 20 kg/mm2 at 425 ° C and that at this temperature the samples possess high plasticity (over 20% elongation).

    Measuring linear contraction of alloys (1962)
    Springer
    Measurement techniques 5 (1962), S. 459-460

    Notes: Conclusions 1. The study of the linear contraction process by means of standard instruments produced by our industry provides simultaneously a highly accurate recording of both contraction and cooling processes of several samples at a time on a single instrument. 2. A rise in the eutectic pause of the temperature curve with an increased sample diameter results in a proportional increase in the time taken by the initial expansion, thus indicating an extended grey iron graphitization process. This holds for grey iron smelted both in ordinary and electric furnaces without the addition of any magnesium, and for cast iron modified by magnesium alone or by magnesium and 75% ferrosilicon. 3. It is known from literature that a rise in the thickness of the case walls reduces the strength of the iron and increases the graphite deposit. In this instance a reversed relationship is observed between the eutectic temperature pause, the duration of the precontraction expansion, the graphite deposit, and the mechanical properties' indices of the grey iron of the above composition. This result requires experimental verification. 4. The total linear contraction of grey iron samples decreases with a rising diameter.
