ABSTRACT: In both
Russian and Western publications, the problem of rolling
ferrous and non-ferrous powders has often been investigated,,but no papers have
dealt with the rolling of aluminum powder. An the present paper, the authors-
demonstrate the possibility of manufacturing sheets of foil made of SAP sinter-
ed aluminum powder) by directly rolling the powder. Under these conditions,
ro I I i ng of h i gh-'qua I i ty sheets requires a certain grain size of-the grade APS
powder. -Rolling may be both cold orho@t (at 300-320C), but the.strips@madeof
heated powder are stronger.- A flow process has been designed.for manufacturing,,-
foil made of SAP by simple rolling. @Samples have been:made with a thickness* of;
I to 0.05 mm. The influence.of the degree of,deformation and of annealing on,'
@@e yitimate strength as well as on the density and hardness, was determined.

of the boron lines. the speotroprojeotor "ACO -1 H was used. The oleo-
trodem were made of electrolytic copper (with openings through which
the powder of the samples can be introduood). For the production of

In order to increase-the spectral sensibility when determining the.bo--'

which were ground off UP.to 5 mm on.their ends. Also the 1Yaporiz&tion;1
vessel was extended to a diameter of 1+ mm. Determinatim of the boron
content was maa.e.easier also by projecting the lower electrodes on !the
aperture of the intermediate diaphragm (3.2 mm) and by the fieleotion
of the arc span (2.5 mm). Time of exposuret 60 sec.; ampemge: 5 A. it,'',

cause thespeotral lines of both are too near each other. Further re-
search work is.necessary in this respect-The absolute sensibility of
