Abstract:
In the present work, the conventional and fracture mechanics properties, mainly, cyclic crack growth rate is assessed in longitudinal, transverse & short-transverse directions in order to find out the effect created by-directionality on the various properties of a high strength steel. The various tests which have been done include hardness, tensile, charpy and fracture
mechanic tests. It - has been found that microstructure is same in the
longitudinal
and
the
transverse directions
and
varies in
the short
transverse
.direction. In
the
case
of hardness, leaving
the
longitudinal
direction
there was
variation in the other two directions. The tensile strength was •highest in the transverse direction whereas the charpy values were lowest in this direction finally crack-growth was lowest in the short transverse direction.
