By means of the neutron diffraction technique the texture of a maraging steel rolled sheet have been determined. The measurements were performed by using a neutron diffractometer installed at the IEA-Rl Nuclear Research Reactor, in the beam-hole n 6. To avoid corrections such as neutron absorption and sample luminosity the geometric form of the sample was approximated to spheric and its dimensions do not exceed that of the neutron beam. The texture of the sample was analysed with help of a computer programme that analyses the intensity of the diffracted neutron beam and plot the pole figure.
