The density, degree of crystallinity, melting temperature, thickness, frequency and type of unsaturated groups accessible and inaccessible to bromine in chloroform, and the frequency of methyl groups have been determined for five polyethylene (PE) films.
Samples of the nominal composition Ba6Ce2TM6Si40 (TM = Au, Pt, Pd) were obtained by high frequency melting the elements in a water-cooled copper crucible (The synthesis with TM = Au was already reported in ref (8).) According to X-ray powder diffraction (XRD), all three as-cast products are polyphased, with the clathrate phase as the main phase.
The Al0.5CoCrCuFeNi high-entropy alloy was synthesized by the medium frequency induction melting furnace.
An ingot of AlCrFeNi2Ti0.5 weighing 2.5 kg was firstly fabricated by medium frequency induction melting.
During the experiments, a large sized CoCrFeNiTi0.5 alloy casting ingot was prepared by a medium frequency induction melting furnace.
Open image in new window Fig. 5 Linear relationship between melting temperature and branch frequency in precision butyl-branched polyethylene [30].
Additionally, trial synthesis of beryllide by a melting process using high-frequency heating was carried out.
As he blew his horn it seemed hot to the touch, melting the notes, turning frequencies into vapor.
Interestingly, compounds that yielded the lowest resistivity were also characterized by increased low frequency melt storage modulus (G′) which indicates the existence of a correlation between the two properties.
In order to achieve homogeneous products of n-type Ti1−xZrxNiSn, Ti1−xHfxNiSn, and corresponding Sn/Sb substituted alloys, the synthesis conditions were tuned by an optimized arc melting technique, an intermediate high frequency melting step, long time ball milling and a multi-step hot pressing technique.
