initial alloy after this aging had a tensile strength of 40.5 kg/mm2, a yield strength
of 37.0 kg/MM2, and an elongation of 17%. The tests*showed that homogenization had
little or no effect on the mechanical properties of Al--Zn-Mg alloys. Small quantities
of refractory elements added to the initial alloy had a small but noticeable effect on
the mechanical properties bul greatly improved the corrosion resistance, especially
zirconium and zirconium coml-ned with titanium. The mechanical properties of alloys
microalloyed with Zr or Zr + Ti were.-tensile strength 45.2 and-39.5 kg/MM2, yield
strength 39.0 and 35.8 kg/mm2, and elongation 14 and 17.22, respectively. The
initial A!-Zn-Mg alloy had a very low resistance to stress corrosion when naturally
aged (service life 6 days) and low corrosion resistance when artificially aged (ser-
vice life from 42 to 76 days). In the majority of cases, microalloying increased the
service life up to 200 days. The beneficial effect of refractory metals on corrosion
resistance increased with higher alloying. The effect of microalloying on the tem-
perature and kinetics of recrystallization was insignificant. in the Initial AI-Zn-ft
alloy the recrystallimation was completed during beating to About 320C. In alloys
containing zirconium, ihe recrystallization began at 310C and was not complete at SCOC

A13STRACT: 25 ingots of AOO aluminum combined with 5% pure Zn and 2% pure -M- and minute
aniounts of various refractory elements (0. 005-0. 1% Zr, 0. 005-0. 1% Ti, 0. 005-0. 1% Be,
0. 005-0. 05001o Cr, 0. 005-0. 050% Mn) were subjected to microstructural analysis and mechani-
cal tests. Part of the ingots was homogenized in a furnace with forced air circulation at 450-
470'C. Itxas established that all these elements, even if added in minute amounts, maelcedly

influence the structure and properties of the incrot. Zr in amounts of up to 0. 05 at - % increases
the size of the macrograin, reduces the size of the dendritic cell, slightly enhances Uie hard-
ness of the ing-ot and inicrohardness of the solid solution in homogenized state, and reduces
hvinorunization time. TI, like Zr, also reduces the dimensions of the dendritic cell,
but unlike Zr, it has an opposite effect on macrograin size, hardness, microhardness of the
solid solution and homogenization time. Be sharply reduces the intracrystalline segreigation
and homogenization time of the ingot. The effect of Be in many cases coincides with the effect
of Zr and is opposite to the effect of Ti. Thus, e.g. Ti reduces the hardness of the iu-zn-Mg
alloy in cast state by 4-5 11 units, whereas Be increasas hardhass by 3-5 units and Zr also

increases it, though to a less significant extent (Fig. 1). This may be to some extent. attri-
butable to the fact that Zr and Be have metallic radii which sharply differ from the metallic
radius of Ti, whereas the metallic radius of Ti is similar to that of Al. Inthe ingots to which
rnoi-e than one refractory element was added, the observed effects were diluted if not

TITLE: Investigation of the Fine Structure of the Alpha Radiation M
of U234 and U235
PERIODICAL; Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, 1960,
Vol. 24, No. 9, pp. 1035 - 1040 234
TEXT:-The authors studied the fine structure of the alpha spectra of U
and U235 by means of a large magnetic spectrograph with double focusing
(Refs. 1 and 2) in the energy range 4150 !.- 4800 kev. A uranium target
235
enriched in U , which was produced by vacuum evaporation, served as the
source. The target had a thickness of "10 #g/cm2. The spectrograph was
calibrated with a group of U 234 alphas. This group corresponds to the
transition of Th 230 to the ground state. Three well-known groups
corresponding to the transitions to the rotational levels of

Th 2,30 (0+- P+_ nnd 4+) wAra found in theoe-rav snectrum of U2.34 (Fix. I and
Table 1). The latter transition (4+) was observed for the first time by
means of a spectrograph. The values obtained for,the energies and the
relative intensities o-,^ the above-mentioned groups are in good agreement
with the results of Refs. 3 - 6. 'he results of the investigation of the
fine'structure of the oC-decay of U235 are given in Figs. 1 - 3 and Table 2.
13 groups of alphas were found altogether. The results published in the
present paper do not contradict those obtained by means of an ionization
chamber (Refs. ? and 8), but differ considerably from the results of Refs.
9 - 11. This is especially true of groups of high intensity (Fig. 2). The
analysis of the data obtained indicates that the fine-structure groups of
the d_~-spectrum of U235 correspond to the transitions to the levels of
23-1. An energy--level scheme of the
four- or five single-particle state's of Th
Th 231 nucleus is suggested (Fig- 3). However, this scheme cannot make a
claim to finality. The determination of a reliable scheme would require
