On Slip Bands Obtained by Tension on Aluminium Specimens

IN RECENT studies'- ' we have been able to reveal
the fine structure of Slip hands : we could also, on
the other hand, determine the influence of deformation
hands and adjacent crystals on their structure.
In the present paper our aim is to define the mutual
relations existing bctwween micro-hardness and slip
bands. We are also examining the influence exerted
by dimensions of the specimen and state of initial
perfection on the development of these slip hands
during plastic deformation.
To avoid any anibiguity, we are explaining below
what we mean by the following phrases :
"Kink band" : unhent zone consisting of two kink
hands in opposite ends.
"Kink band": in knee" zone of great curvature
separating two unbent ,zones.
"Deformation band" : kink band, kink hand in
knee, secondary slip hand.
"Slip line"' : intersection of the surface of the
specimen and only one slip plane.
"Slip band" ; grouping of parallel slip lines.
