  • Metallographic Analysis and strength investigation of different becu joints in the temperature range rt 350 c
    Journal of Nuclear Materials, 1996
    Co-Authors: A Gervash, R N Giniatouline, I Mazul, A A Ganenko, L S Gitarskij, V S Sizenev, D A Davydov
    Abstract:

    Abstract The goal of this work is to estimate the strength and structure of different BeCu joining techniques. Brazing, diffusion bonding and joint rolling methods were chosen as ITER BeCu joint method candidates. Selected for ITER application BeCu joints were produced as technological plates (30–50 mm × 50–100 mm × thickness). All samples for further investigations were cut from initial technological plates. To compare mechanical strength of selected BeCu joints tensile and shearing tests of chosen candidates were carried out in the temperature range RT—350°C. The Metallographic Analysis of the BeCu cross-section was also done. Preliminary results of these tests as well as Metallographic Analysis data are presented. The industrial possibilities of producing required for ITER full scale BeCu joints are discussed.

  • Analysis of Damage of Solder Joint of Heat Exchanger
    Solid State Phenomena, 2017
    Co-Authors: Pavel Gejdoš, L. Páleníková, Lenka Klakurková, Miroslava Horynová, Martin Juliš, Jiří Švejcar
    Abstract:

    The paper focus on the Metallographic Analysis of damaged heat exchanger made of high‑alloy austenitic steel by soldering. The object in question is a soldered joint of main mounting plate of the heat exchanger and first heat exchanging plate of it. In this part of the heat exchanger after the vibration and pressure test crack appeared. The subject of the Analysis is the evaluation of the microstructure of the solder joint (high-alloy austenitic steel and copper), and evaluation of the appeared crack. The problematic is solved with aid of Metallographic Analysis of the microstructure of the material, using light microscopy and scanning electron microscopy and the EDS microAnalysis of chemical composition.

  • Application of Metallographic Analysis Techniques for Detection and Identification of Spray Paint Defects
    Solid State Phenomena, 2017
    Co-Authors: Michaela Remešová, L. Páleníková, Lenka Klakurková, Ivana Ročňáková, Ladislav Čelko, Jozef Kaiser
    Abstract:

    The paper is focused on the Metallographic Analysis of spray paint films with defects. The painting has two important roles. Firstly, it protects the substrate material (ferrous, nonferrous and plastic) and secondly, it improves the appearance of the surface. Appearance and quality of painting film play an important role in the industry (automotive, aerospace, consumer electronics, etc.). Defects of spray painting film, which have a negative effect on the appearance of the product, can be detected and further analysed by common methods used in metallography. Such methods are very effective tool for revealing the cause of defects and their elimination within the technological process (degreasing, cleaning, pickling, drying, technological discipline, etc.). In this paper, defects were characterized by high-resolution digital microscope (LM) and scanning electron microscope (SEM) equipped with energy dispersive X-ray analyser (EDX).

  • Analysis of Coupling Segment of Belt Conveyor
    Key Engineering Materials, 2015
    Co-Authors: Lenka Klakurková, Ladislav Čelko, Martin Juliš, David Jech, Jiří Švejcar
    Abstract:

    The paper focuses on the Metallographic Analysis of damaged belt-conveyor coupling segments made of high-alloy austenitic steel. The object in question is a weldment – a bar with a ring welded on it at either end. The subject of the Analysis is the evaluation of the microstructure of the base material of the two components (weldment and weld metal), the quality of the execution of the weld joints, subsequent heat treatment of the weldment, and the overall state of the component part after operational loading. The suitability of the design solution of the whole weldment is also discussed. The problematic is solved with the aid of a Metallographic Analysis of the microstructure of the material, using light microscopy, scanning electron microscopy inclusive of the EDS microAnalysis of chemical composition, and microhardness measurement.
