Abstract: ECCC is a voluntary grouping formed in 1991 to co-ordinate Europe-wide development of creep data to be used to design components for high temperature plants, bases on a Memorandum of Understanding, signed by all partners. The ECCC is deeply involved in EU coordination for the development of knowledge on the damage caused by the creep phenomenon and the consequent reliability assessment activities. Strong links exist with the technical committees of the European Standard organizations, giving an efficient network to mutually exchange of technical information relating to current/future activities for the improvement or development of new materials. For several years ECCC (1991-2005) concentrated efforts by EU support. Nevertheless, revitalization of ECCC has been generated by definition of Joint Industrial Project (JIP) started in 2011 and still running (JIP4). ECCC has a very strong link to industrial applications and it is presently organized in four Work Packages: WG1 on common procedures, data generation/assessment and three material specific Working groups: ferritic steels, austenitic steels, nickel-based alloys. Two main outputs are ECCC data sheets and ECCC Recommendation Volumes. The ECCC activities are almost completely carried out by members’ contribution-in-kind. The ECCC plays a part of its role, in term of generation of design properties for new materials introduction into power plant and related applications. It therefore engages a crucial role in assessing and realising the potential of new developments.

Abstract: Compared to discrete manufacturing, sheet material is produced in a continuous manufacturing process with several dimension and volume changes. This includes thickness reduction by rolling and width and length changes by slitting and cross-cutting. Along the process chain, this happens several times using different manufacturing facilities, where each work step is usually followed by coiling. Each of these machines records high-frequent production data in a time-based manner. General research topics in this field [1, 2] aim to assign the time-based records to the related section of the alloy sheet (length-based). This paper deals with challenges concerning the identification of strips and the assignment of the corresponding process data. In a particular application, the coil orientation for each process step is calculated and documented for a given part of the production process. This is a necessary precondition for further process data assignment. Furthermore, the effort for certain manual tasks can be reduced by using the calculated coil orientation.

Abstract: There has been a lot of interest in the sustainability aspects of 3D Printing, also known as Additive Manufacturing, due to its potential for resource conservation, localized production, and optimized and adaptive designs. However, quantifying these sustainability advantages has proven to be a challenging task. Several tools have been developed to address this endeavor, and this article provides an overview of some of these tools, focusing on their application in the Manufacturing and Building & Construction sectors. The most widely adopted studies are Life Cycle Assessments (LCAs), which help us understand the environmental impact through all stages of a product’s life, and are key to identifying best practices and opportunities for innovation. By exploring the sustainability dimensions of 3D printing through the lens of life cycle analysis, this article aims to shed light on the crucial role that LCAs play in assessing the environmental implications of 3D printing practices. Furthermore, it underscores the importance of leveraging this knowledge to drive sustainable practices, improve the efficiency of the 3D printing industry, and pave the way for a more sustainable future.

Abstract: The high-pressure torsion (HPT) method, which is currently used as a severe plastic deformation process to develop advanced structural and functional materials, was first introduced to the public by Bridgman in 1935 as a tool to investigate the mechanism of deep-seated earthquakes. The HPT method was recently introduced as a new platform to simulate astronomical impacts on a miniature scale. Frequent impacts by small solar system bodies (meteoroids, asteroids and comets) about four billion years ago are considered a possible pathway for the delivery or synthesis of essential biomolecules required for life on the Earth. The application of HPT to glycine amino acid led to new justifications for some astronomical phenomena reported in comets or on the Earth such as the formation of alcohol. The extension of this application also led to the introduction of inorganic-biomolecule composites as new functional materials with good biocompatibility.

Abstract: The effect of artificial sand on the amount of core gas emission was examined. Mass loss by thermal decomposition of the binder was evaluated when resin-coated sand (RCS) with various amounts of artificial sand was exposed to high temperature. Compared to natural sand, the mass loss and temperature variation of artificial sand was reduced. It was confirmed that this is because the contact area between the two particles is reduced when the binder bridge is created between the foundry sands. Therefore, the surface morphology of the artificial sand has ragged surface, so that the heat conduction area is decreased.
