T1 - How to extract continuum materials properties for (lead-free) solders from tensile tests and nanoindentation experiments N2 - Fabrication of modern microelectronic components requires miscellaneous solder materials for joining. In order to guarantee the quality of the manufacturing process and the reliability of the resulting solder joint it is necessary to know the material properties of the joining parts and of the solder materials. In particular Young’s modulus, yield stress, and the hardness are of great interest. Moreover, a complete stress-strain curve is important for a detailed material characterization and simulation of a component, e.g., by Finite Elements (FE). The miniaturization of modern electronic products with small solder joints allows only fabrication of very small-sized specimens. Because of this miniature tests are used for measuring the mechanical properties of the solders in the experimental investigations of this paper. More specifically two miniature tests are presented and discussed, a mini-uniaxial-tension-test and a nanoindenter experiment. In the tensile test the axial loading is prescribed, the corresponding extension of the specimen length is recorded, both of which determines the stress-strain- curve directly. The stress-strain curves are then mathematically analyzed by assuming a non-linear relationship between stress and strain of the Ramberg-Osgood type and fitting the corresponding parameters to the experimental data by means of an optimization routine. For a detailed analysis of very local mechanical properties nanoindentation is used, resulting primarily in load vs. indentation-depth data. According to the procedure of Pharr and Oliver this data can be used to obtain hardness and Young’s modulus but not a complete stress-strain curve, at least not directly. In order to obtain such a stress-strain-curve, the nanoindentation experiment is combined with FE and the coefficients involved in the corresponding constitutive equation for stress and strain are obtained by means of the inverse method. Finally in this paper, the stress-strain curves from nanoindentation and tensile tests are compared for two materials, namely aluminum and steel and differences are explained in terms of the locality of the measured properties.

T1 - Three-dimensional microstructure visualization of porosity and Fe-rich inclusions in SiC particle-reinforced Al alloy matrix composites by X-ray synchrotron tomography N2 - Microstructural aspects of composites such as reinforcement particle size, shape, and distribution play important roles in deformation behavior. In addition, Fe-rich inclusions and porosity also influence the behavior of these composites, particularly under fatigue loading. Three-dimensional (3-D) visualization of porosity and Fe-rich inclusions in three dimensions is critical to a thorough understanding of fatigue resistance of metal matrix composites (MMCs), because cracks often initiate at these defects. In this article, we have used X-ray synchrotron tomography to visualize and quantify the morphology and size distribution of pores and Fe-rich inclusions in a SiC particle-reinforced 2080 Al alloy composite. The 3-D data sets were also used to predict and understand the influence of defects on the deformation behavior by 3-D finite element modeling.

A1 - Pitkänen, J. A1 - Ronneteg, U. T1 - Human factors approach to the reliability of NDT in nuclear waste management in Sweden and Finland N2 - Nuclear power industry has the responsibility to manage and dispose of all radioactive waste from its plants. Finnish Posiva and Swedish SKB are leading in the world in the development of disposal of spent nuclear fuel. Their method consists of encapsulating spent nuclear fuel in copper canisters and depositing them in the bedrock at a depth of about 500 meters for the next 100 000 years, leaving the radioactivity to decrease naturally through the decay of the radioisotopes in it. The copper canisters, consisting of a copper tube, a lid and a bottom (which make the outer shell) and an insert made of a cast iron, need to be inspected for their structural integrity to ensure no critical defects are present in the materials and welds that could lead to a leakage of the waste into the environment. Data acquired by 4 different non-destructive testing (NDT) methods (i.e. UT, ET, RT and VT with a remote camera) are evaluated by skilled human operators and therefore could be subject to human error. Human Factors approach lies in identifying potential errors made by the human, their causes and ways of preventing them. A customized Failure Modes and Effects Analysis (FMEA) was conducted to anticipate possible human failures during the data evaluation. The results led to designing several experiments (e.g. diffusion of responsibility within the 4-eye principle, over trust in automated systems) which are being experimentally tested in ongoing projects. The results are expected to lead to the optimization of the procedures followed by the NDT operators and consequently to the improvement of the overall NDT reliability.

T1 - The charge of solid-liquid interfaces measured by X-ray standing waves and streaming current N2 - Measurements of ion distributions at a charged solid–liquid interface using X-ray standing waves (XSW) are presented. High energy synchrotron radiation (17.48 keV) is used to produce an XSW pattern inside a thin water film on a silicon wafer. The liquid phase is an aqueous solution containing Br and Rb ions. The surface charge is adjusted by titration. Measurements are performed over a pH range from 2.2–9, using the native Si oxide layer and functional (amine) groups as surface charge. The Debye length, indicating the extension of the diffuse layer, could be measured with values varying between 1–4 nm. For functionalized wafers, the pH dependent change from attraction to repulsion of an ion species could be detected, indicating the isoelectric point. In combination with the measurement of the streaming current, the surface charge of the sample could be quantified.
