Most of the weld procedure specifications, guidelines and standards targeted at HACC avoidance recommend preheating procedures. Application of such regulations to multi-pass welds of modern high strength structural steels with yield strengths of up to 1300 MPa is very limited. Actually there is no decent knowledge and only an empirical experience how to weld such joints in real components subjected to a respective shrinkage restraint. Consequently, an increasing number of failure cases, partly of catastrophic dimensions, have been reported in the present decade. The present contribution is targeted to close this knowledge gap by elucidating the principal effects of various inhomogeneous Hydrogen Removal Heat Treatment (HRHT) procedures on the HACC avoidance in high strength structural steel welds. As a typical representative in the upper yield strength range of this category of materials, a S 1100 QL weld using UNION X96 filler wire has been chosen. The results were achieved by indirectly coupled thermal, structural and hydrogen diffusion finite element modeling of HACC in single-layer and five-layer welded V-bevelled butt joints with plate thicknesses of 20.0 mm and 12.0 mm, respectively, at realistic restraint conditions and have been partly been confirmed by respective Instrumented Restraint Cracking (IRC) Tests. The numerical simulations are based on the interacting three local effects on HACC, i.e. local microstructure, local mechanical load and local hydrogen concentration. HACC has thus been regarded as a cracking phenomenon occurring, if the local mechanical load in a specific microstructure exceeds the limit for the respective hydrogen concentration. The various heat treatments proposed in literature, guidelines, specifications and standards, i.e. sole preheating, controlled interpass temperature, combined preheating and controlled interpass temperature application as well as postheating have been investigated with respect to their effects on the mechanical loading of the butt joints in terms of stresses and strains as well as on the hydrogen removal capabilities. As a particular item, a numerical model for Hydrogen Assisted Stress Corrosion Cracking (HASCC) has been developed further that it can be applied to HACC, in order to study, how such heat treatments influence crack initiation and propagation. By such modeling procedures as the most important results have been achieved: I. Further development and adaptation of a model for hydrogen assisted cracking to HACC and usage validation of the model for this material. II. Evaluation of the effects of pre- and postheating as well as interpass temperature on the stress-strain distribution in multi-pass welds. III. Clarification of the difference between single- and multi-pass welding with respect to stress-strain and hydrogen distribution as well as to HACC initiation and propagation. IV. Establishment of practical hydrogen removal heat treatment diagrams. V. Assessment of the effects of the amount of hydrogen picked up during welding on crack location and propagation.

T1 - Measurements with compound refractive lenses at the "BAMline" N2 - A set of compound refractive lenses (CRLs), mounted on a silicon wafer, was obtained from the Institut für Mikrostrukturtechnik Karlsruhe. The CRLs were characterized at the BAMline at the synchrotron BESSYII in Berlin. It could be demonstrated that beam diameters below 1 µm can be obtained. The beam size accepted by the lenses is (140 × 140) µm2, thus the intensity gain in the micrometer spot, including absorption, is about 15,000. It is possible to switch between different beam energies within a few minutes. First results of scans and the application of the lenses for MicroXANES (X-ray absorption near-edge structure) measurements are presented in this paper. Also, the possibility of MicroEXAFS (extended X-ray absorption fine structure) measurements is discussed.

Oscillating sliding friction was investigated with a pin-on-disc configuration in high vacuum (10-5 mbar) at room temperature, -40 °C, +100 °C and +160 °C. The contact pressure was 1 MPa and 7 MPa respectively , the maximum sliding velocity 0.1 m/s. Furthermore, tests in ultra high vacuum (10-9 mbar) were carried out with flat and spherical pins at 1 MPa and 60 MPa respectively. Among the tested materials MoS2 filled PEEK shows the best tribological performance in vacuum. Particularly, in the lower temperature range and at higher loads the friction behaviour is improved by MoS2 content.
