PHYSICAL METALLURGY OF FAST BREEDER REACTOR CLADDING MATERIALS AND REFRACTORY METALS. [PDF]
, 1969 Studies on Re - Mo - W alloys led to lower cost production procedures and greatly improved room temperature ductility properties of powder metallurgy materials used for fast breeder reactor fuel cladding materials. Data are presented for ductility, grain size, hardness, recrystallization, and changes in aging at temperatures up to 2000 deg C for ...

Eastern-European Journal of Enterprise Technologies, 2019 X-ray diffraction phase analysis of samples performed on a DRON-6 diffractometer has shown that the processes of CaWO 4 transition to WC and W 2 C had the highest probability in the temperature range of 1,173–1,473 K. The end-product CaWO 4 , thermally treated with carbon, was represented by carbon in oxycarbide and carbide phases.

Notes on Metallic Affect: Metallurgy and New Materialism
FORUM: University of Edinburgh Postgraduate Journal of Culture & the Arts, 2014 This paper follows Theodore Wertime, twentieth century historian of metallurgy, spy turned survivalist. Wertime's fascination with metallurgy is related to the Smith in Deleuze and Guattari and the mythical Alchemist of Mircea Eliade's work; also explored are notions of the Cyborg and of Geotrauma.
