An investigation of the "extrusion effect" (increaued strength as a result of the extrusic
process) in aluminum-magnesium alloys with additions of chromium and manganese (together
and separately) shows that these alloys retain their Increased strength even after cold
drawing. It -is further shown that the extrusion effect is preserved at el-zvated temperatur
(3000 C) and is observed both in the short-time strength test and in the long-time hardness
test. There are 10 references, of vhich are Sovietl and 2 German.

TITLE: Processes Occurring During Homogenizing Anneal of Aluminum

ABSTRACT: Alloys of the type AMts and D16 containing 1-2/o Mn,
- 4. 6~o Cu, and - I*4(yo Mg, were subjected to homogenizing
anneal at temperature. of 500'C (12-240 hrs) and 6300 ( 3-24
hrs), followed bextruding operations resulting in a reduction
of 9.3.4/o at 4Z0 finally, a portion of the specimens was
quench-hardened at 500 . Microstructural and X-ray diffraction-
study methods were employed in the investigation. In the course
of the homogenizing anneal of Al alloys containing Mn, the pro-
cess of dissolution is accompanied by a concurrent process of
.decomposition of the solid solution of Mn in Al. Prolonged
homogenization of ingots produces intensive decomposition of

chemical compounds which are separated out from the solution, sharply
reduces the strength of the ingots, and increases the plasticity of the
extruded i:ods. At a temperature of 5000, homogenizing arneal of the
Mn-free D16 alloy is not accompanied by decomposition of the solid solution.
As the Mn content of the alloys is increased, the decomposition of the solid
solution of Mn in Al is intensified. As the Mn content of rods extruded from
ingots which have not been subjected to homogenizing dnneal is inireased from
0 to 0. 94'76 the o- of th2 rods increases from 47 to 64 kg/mm and the
(T from i9 to 43 4/mm ; in the case of rods extruded from ingots which
9 0
have been subjected to a homogenizing anneal at 500 for a period ~f 240 hours,
an increase in Mn content i 2creases the ab from 4 6 to 51 kg/mm , and the
T s from 28 to 31 kg/mm. , i. e. , this process of homogenization relieves
the press effect entirely; this is explained by the intensive coagulation in the
ingot of the products of decomposition of the solid Mn solution in Al.

PERIODICALt Zavodskays, Laboratoriya, 1959, Vol 25, Nr-69 pP 703-704 (USSR)
ABSTRACTz The tendency of the Al-Mg alloys (with an increased
magnesium content) to corrosion under tension is determined
according to the structural character, i.e. the presence of
almost continuous bmmdaries of the A-phase (or a chemical
intermediate compound) along the grain boundaries. In the case
under review the alloy Amg6T was investigated with a thermal
treatment. The degree of decomposition of the solid solution
and the distribution of the decomposition products in the
grains of the solid solution were taken into donaideration.
The samples were supplied by foils 210*15v2 mm that were
submitted to different thermal treatments and thereupon
dropped into a corrosion medium (3 % NaC1 and 0.1 % H202 in
Card 1/2 water). Experimental results obtained reveal (Table) that

only after turning on to 2000 an increased tendency towards
corrosion under tension occurs. Turning on to 500 and 1000
affects the struoture but little. Turning on to 3000 effects
the coagulation of the particles of the (1-phase and the
formation of isolated particles at the grain boundaries, in
which case the corrosion resistance rises again. Figures are

TEXT: A study of the influence of manganese and chromium
additions to aluminium alloys containing 6 to 9% magnesium on the
mechanical properties at room and elevated temperatures has been
carried out. The aim was to determine the optimum total quantity
and the optimum ratio of the manganese and chromium contents.
Table 2 shows the alloys tested. Billets of the alloys were cast
by continuous casting at 280 mm/min. The casting temperature was
69o to 7000C. 50 mm were cut from both ends and rejected.
The billets were homogenized at 4800C for 36 hours. They were
machined, hot rolled to 6 mm thickness, annealed and cold rolled to
1.8 mm. Tensile testa were carried out at room and elevated
temperatures. All the samples tested were annealed at 350*C for

(Al - 6.3% Mg - o.6% mn - 0-15% Ti - 0.2% Fe - 0.25% Si) in relation
to its structure was investigated, Strips, 210 x 15 x 2 mm, of the
alloy were heated at 350*C for I hour, water-cooled and then heated
at 50*C for 24 hours, 100*C for 24 hours, 200*C for 5 hours and
300% for 5 hours. Some of the samples were quenched in water
from 450*C- The plates were bent in a loop and immersed in
3% NaC1 and 0-lys H202 In water. The solutIon wan changed after
every 15 days. The criterion of corrosion resistance was the time
taken for cracks to appear in the sample, visible to the naked eye.

Cracking was not observed when the samples had been annealed at
low (50, 100*0 or high (300*0 temperatures. The samples
annealed at 200*C cracked after 16 days. Microstructural
examination showed a clear connection between structure and
tendency to corrode. Specimens were prepared by electrolytic
polishing and etching in a 9% solution of H3PO4 for 30 min, The
specimen quenched from 4500C was homogeneous (Fig.la) after
annealing at 350'C, there was a heterogeneous structure but the
grain boundaries were not continuous (Fig.lb). Annealing at
50 and 100% for 24 hours resulted in no change In structure;
cracking did not occur after 125 days. Heating at 2009C for
5 hours gave the structure in Fig.lB. The grain boundaries are
very sharp. The P-phase forms a continuous boundary round the
grains - a structure unfavourable from the point of view of stress
corrosion. Fig.2 shows the formation of an intercrystalline
crack in this specimen. Heating at 300*C results in
agglomeration of the precipitate and the P-phase is no longer
continuous round the grains (Fig.12 ). The samples did not crack
after 125 days. Thus microscopic analysis can be used as a method
of control of the corrosion resistance of AMg6. This is

for alloys of medium Mg and Si content (0.8 and 0.9%, respectively), and
of higher fig and Si content (1.0 and 1~21/6, respectively). Mn which is one
of the constituents of standard Aviall and causes a definite strengthen

weakens these alloys an air-quenching. The above weakening is observed
with simple Avial's as well as with those containing additions of Cu
(2%) and Zn (2%), Lite Jcgree of weakening heing the inore pronounced the
greater the Mn content. When high strength charac teri sties are required
for components after air-cooling or after cooling by any other Method
which given a rate slower than that obtained by water quenching, Mn-free
Avialls are recommended (particularly for welded structures). Mn-free
Avial's can be considered its self-quenchtnX alloys. Avial's with an
addition of 2% Zn deserve attention owing to the high mechanical proper-
ties exhibited by sheet after air quenching. Sheets of this alloy after
quenching in air hitve practically the oinme strength as after (juanching,
in water, the str(!iirt,fi boing, greater than that of' Zn-free Avialls.

All-STRACT: The effects of 0. 001 - 1. 0% Do on the oxidizability and mechanical properties
of magnalium at room and high temperatures were studied on four alloys, each containing
9''IV *.%I-, nnd varying amounts of '.%In (0. 4 - 0. G%), Ti (0. 0 - 0. 2%) and Cr (00 - 0. 2%).

(3G lirs, -180C) Ing.ts, hot rolled crosswiae to strips 6 mm thick, then lengthwise to sheets
1. 8 mm thick. The sheets wore annealed at 350C. Results indicate that Be in these con-
centrations does not affect tensile strength, relative elongation or yield point. The latter
