the information given in the text a.ndicates that t.ho Lrol:r:u c .~~~es

was assessed by bending tests conduct ed on argon-a~:rc welded t ~; st
pieces. The results are re~roducedi in Fig. 10, where the angste
(deg) through which the test piece could be bent before cracl:in� is-
plotted against the Cr content in ~'i-Cr (continuous curves} and
Ti-Cr-Al (broken curves) alloys. The gradual reduction iii the
ductility of the welds with increasing Cr content :in the alloys u,;~s
attributed to an increased 13egree cif e~upersaturati.l~n of the mart:an-
sitic phase formed during welding. Low ductility of the welds i.n
~ alloys with the critical (near 9;~) Cr coat ent was ~3ue to tt~-e
presence of the w-phas�. Haigh ductility of the weads in tl~-e 12� Cr

loss of ductility of the welds in binary 15�o Cr alaoy was due to

s~lloys of this group quenched from the a + ~ range retained the
metastable Q ~ - arad ~-phase which d�composed during the low--t empcara-

hardness pf the q~ ~;r-Ti alloy incr�ea$ed consider~-b].y after ageing
at 500 Fund ~00 QC and decreased after ageing at 50p and 600 �C, the

decomposition of the c~-phase. The hardness of the q�; Cr - 3�; Al-Ti

quench and age-treated VT 14 ha~~ a tensile: strength of 120-1~~0 k~;r,rr~mz and an
elongation of ?-12%. Optimal quench is in water from 860-E~~30�, v~rith aging a.t
480-500� for 12-16 :hrs. The he~~ting time; of rod material at pre-ciue-ic;h tempera-
ture may be limited to approxim~ibely l5 rain, The VT 14 alloy is e:xtretnely sensi-
tive to overheating during plastic, hot deformation and heat treatment. A heating of
the alloy to above 920-930� leadu~ to a sharp impairment of the rr;eci~ani.cal prof>erties
of the alley after hardening heat treatment. Hence, hot working should be p~erforn~ed
at T not to exceed 920-930�, with a reduction in area of the metal .at that te~mperati~re
of not less than 50%. There are 22 figures and 1 (unnumberF:d) table ; no i�eferenc~~~a.

Thermal destruction of polymers ... Bt t8/H2o3
The butane fsaotion in the dastructit-n products of PE oonsists of but~sne-t,
ois-butane-2~ and trans-butane-2. Qn the basis of polarographic data,
pentane-2 is present in much smaller amounts than pentane-t. On the 'basis
of the ideas of isomerization of radicals in destruction (Ref. t), it must
be assumed that butanes are formed in the destruction of Pr by the follo~-

It had to be established Whether ozor~idee wars ales 'form�d from the aol~

method for gaseous clef ins was develc-ped Which proved to be particular;,
convenient in chromatographic purification. Ethylene, propylene, isoh~
