The radial strain in an ICE railway wheel hoop was scanned over the cross section perpendicular to the hoop direction. Only in the middle part of the hoop cross section compressive strain were found. In a band between a distance of 5–12mm from the

The outline of a new instrument is described that is dedicated to stress diffractometry at the Budapest Research Reactor (BRR). The first check of the instrument is planned at the beginning of 2001.

The three-dimensional neutron depolarization (ND) technique has been applied to characterize the bulk magnetic domain structure and the spatial distribution of the magnetic anisotropy in amorphous Fe 40 Ni 40 B 20 , which was annealed under the appli

The magnetic properties of the nanocrystalline soft-magnetic alloy Fe 73.5 Nb 3 Cu 1 Si 13.5 B 9 have been investigated with the 3D neutron depolarisation technique as a function of temperature and external magnetic field. Around the reverse coercive

A stress rig is constructed to make in situ neutron diffraction possible on tensile test specimens. The lattice spacing of the (1 1 0) reflection of a ferritic steel having nonuniform cross-section is measured both parallel and perpendicular to the a

Temperature dependence of the (1 1 1) reflection of Cu was measured in Fe 95 Cu 5 alloy and high purity Cu. While the pure Cu follows linear dependence both the internal stresses on the grains and their thermal expansion coefficient undergo several c

Carbon fibres made by pyrolysis of polyacrylonitrile textile fibres are investigated using neutron small angle scattering. The average size of the skin-layer is determined. Small voids of discrete values of radius of gyration are observed. A simple m

Disaccommodation of the complex magnetic susceptibility was measured in different homogeneous and inhomogeneous iron alloys. In homogeneous alloys, the real and imaginary part of the complex susceptibility change in parallel, and carry the same infor

The hysteresis loops of amorphous Fe80B20, Fe40Ni40B20, and Co58Ni10Fe5Si11B16 alloys are investigated before and after various heat treatments in zero, dc, and ac magnetic fields and under different stress conditions. After definite treatments wasp-
