Erosion Phases in Two Types of Cement Pastes Containing Limestone Exposed to Sulfate Attack Fengchen Zhang a, Yun Zhao b and Fuwan Zhu c College of Mechanics and Materials, Hohai University, Nanjing 210098, China azhangfc67@163.com, b zhaoyun900045@qq.com, c 973199228@qq.com Keywords: thaumasite, ettringite, gypsum,portlandite Abstract.
TSA has more deterioration to all cement-based material than conventional sulfate attack because its target is C-S-H gel.
Cement-based material containing limestone is more susceptible to TSA.
Two bands with frequencies at 670, 499 cm-1 can be observed in 0-1mm layer, which are characteristic of the octahedral [SiO6] groups and indicates the presence of thaumasite because thaumasite is the only mineral containing Si in octahedral coordination[11] in all cement-based materials.

VHCF strength of helical compression springs - Influence of heat treatment temperature before shot peening Isabell Brunner1, a *, Desislava Veleva1, b, Jörg Beyer1, c, Matthias Oechsner1, d 1State Materials Testing Institute Darmstadt, Chair and Institute for Materials Science, Technische Universität Darmstadt, 64283 Darmstadt, Germany abrunner@mpa-ifw.tu-darmstadt.de, bveleva@mpa-ifw.tu-darmstadt.de, cbeyer@mpa-ifw.tu-darmstadt.de, doechsner@mpa-ifw.tu-darmstadt.de, *corresponding author Keywords: Helical compression springs, SiCr-alloyed valve spring steel, very high cycle fatigue test, heat treatment temperature Abstract.
To analyse the influence of different materials and production parameters on the VHCF fatigue strength of helical compression springs, a project was initiated at the Institute for Materials Technology at the Technische Universität Darmstadt [2].
By adjusting production parameters, the reliability of helical compression springs can be improved for a very high number of cycles even for cost-efficient spring wire materials.

Matano to the Quantitative Analysis of Diffusion Phenomena Wolfgang Sprengel1,a and Masahiro Koiwa2,b 1Institute of Materials Physics, Graz University of Technology, Graz, Austria 2Department of Materials Science and Engineering, Kyoto University, Kyoto, Japan aw.sprengel@tugraz.at, bmkoiwa@zd.ztv.ne.jp, Keywords: Boltzmann, Matano, diffusion coefficient, analysis, history.
In text books of metallurgy or materials science this condition is illustrated as the origin of a plane which divides the area below the c(x) curve into two equal parts, an equivalent drawing can also be found in Matano’s paper (see Fig. 5b).
Often expressions found in textbooks of metallurgy or materials science concerning the “Matano plane” are misleading or simply wrong, as they do not correctly refer to the original paper by Matano.
In this sense, cleverly designed diffusion experiments in supercooled liquids might lead to new frontiers in materials science.

The results also indicate that the stress redistributions of the hoops and the concrete sections are obvious, and long-lasting when specimens achieve the ultimate bearing capacity after the yield of the rebar and local damage of concrete materials, at this time the strain of the specimens develops a lot, especially stress - strain curves of specimens with high-strength hoop all show a wide and flat top.
