Bainitic microstructures occur increasingly in modern, low-alloy multi-phase steels. A knowledge of the type of bainitic microstructure formed as a result of the alloy composition and manufacturing process used is important in enabling the required level of strength to be achieved. The morphology of the cementite precipitated plays an important role in identifying the phases present. Currently, in order to characterise and evaluate the sub-microscopic cementite formed the lengthy and expensive process of transmission electron microscopy (TEM) is used. The work presented here demonstrates that with the use of an optimised method of specimen preparation and examination, the morphology of the cementite precipitate in bainitic microstructures may also be examined using high resolution scanning electron microscopy (HRSEM) and, in addition, the quantitative characteristics such as particle length, number and distribution evaluated. Compared with TEM, this optimised method of specimen preparation and examination will in future permit statistically more accurate and thus more cost efficient investigations to be carried out on the formation ofcementite. © Carl Hanser Verlag, Münchan.

When it comes to characterizing modern ultra-high-strength steels, classical metallography is faced with enormous challenges In the context of etching, where several phases occur at one time and in the context of resolution, where grain sizes are in a range of a few μm. This article is to show how it is still possible, by means of classical etching technique and images made by light microscopy, to perform quantitative microstructural evaluations despite difficult preconditions. Classical etching techniques developed by Beraha and LePera, which have been in use for decades now, are deployed when contrasting conventional steels for a qualitative and quantitative evaluation and their results are being compared. Investigations with scanning electron microscopes are made to review the results. © Carl Hanser Verlag, München. Source

Annual Technical Conference - ANTEC, Conference Proceedings | Year: 2013

The aim of this work was to investigate the effectiveness of industrially available additives (with different chemical nature) for compatibilization of HDPE - PA6 blends in terms of mechanical and rheological properties. Furthermore, the morphology of the samples should be assessed to get deeper insights into the interaction of the compatibilizer with the two immiscible polymers. We found, that it is possible to compatibilize immiscible blends via the addition of industrially available additives, as well as that the chemical nature of said compatibilizers and the concentration in the blend influence the various investigated properties, like impact strength and morphology.

Zentralsterilisation - Central Service | Year: 2015

An essential part of the core performance of hospitals is provided in the operating room (OR). For the time-coordinated provision of the necessary resources (e.g. patient, surgical team, information, surgical material), the effective and efficient, high-quality and flexible supply of sterile goods is a relevant supporting process. At this point, different challenges can be identified concerning the overarching coordination and implementation of the sterile supply process. The question is: What kind of improvements can be attempted and implemented to move towards a concerted and overarching supply process on needs-based (targeted/ effective) and efficient (optimized use of resources) sterile services for hospitals? Within the framework of two research projects, 13 experts working at a hospital focusing on tertiary (specialized) care were interviewed on relevant improvements in the sterile supply process. The survey was conducted as a qualitative longitudinal study based on interviews and observation. It highlighted a potential for improvement in various main categories: external, OR, CSSD, transport, information/communication and organization. Furthermore, short-, medium- And long-term measures for improvement were developed, significant demonstrating the importance of an interdepartmental and interdisciplinary knowledge and communication management strategy.

The Ambient Assisted Living (AAL) market is still in an early stage of development. Previous approaches of comprehensive AAL services are mostly supply-side driven and focused on hardware and software. Usually this type of AAL solutions does not lead to a sustainable success on the market. Research and development increasingly focuses on demand and customer requirements in addition to the social and legal framework. The question is: How can a systematic performance measurement strategy along a service development process support the market-ready design of a concrete business model for AAL service? Within the EU funded research project DALIA (Assistant for Daily Life Activities at Home) an iterative service development process uses an adapted Osterwalder business model canvas. The application of a performance measurement index (PMI) to support the process has been developed and tested. Development of an iterative service development model using a supporting PMI. The PMI framework is developed throughout the engineering of a virtual assistant (AVATAR) as a modular interface to connect informal carers with necessary and useful services. Future research should seek to ensure that the PMI enables meaningful transparency regarding targeting (e.g. innovative AAL service), design (e.g. functional hybrid AAL service) and implementation (e.g. marketable AAL support services). To this end, a further reference to further testing practices is required. The aim must be to develop a weighted PMI in the context of further research, which supports both the service engineering and the subsequent service management process. © 2015 The authors and IOS Press.
