Influence of Friction Riveting Parameters on the Dissimilar Joint Formation and Strength. [PDF]
Materials (Basel), 2022 Friction riveting represents a promising technology for joining similar and/or dissimilar materials of light-weight components. However, the main drawback of the technology is that it is primarily used only with special machines for friction welding that have a force control. In this study we used accessible CNC machines with a position control.

Fidelity-Commensurability Tradeoff in Joint Embedding of Disparate Dissimilarities [PDF]
Journal of Classification, 2016 In various data settings, it is necessary to compare observations from disparate data sources. We assume the data is in the dissimilarity representation and investigate a joint embedding method that results in a commensurate representation of disparate dissimilarities.

Characterization of Mechanical Heterogeneity in Dissimilar Metal Welded Joints [PDF]
Materials, 2021 Dissimilar metal welded joints (DMWJs) possess significant localized mechanical heterogeneity. Using finite element software ABAQUS with the User-defined Material (UMAT) subroutine, this study proposed a constitutive equation that may be used to express the heterogeneous mechanical properties of the heat-affected and fusion zones at the interfaces in ...

Residual Stress Generation in Brazed Tungsten Dissimilar Joints [PDF]
IEEE Transactions on Plasma Science, 2016 Understanding the residual stress state in brazed joints is crucial for the operational design and lifetime performance of the part in service. High-magnitude residual stresses are expected in the joined materials following cooling from brazing temperatures (≈950 °C) due to large mismatches in the thermal and mechanical properties.

Carbon Migration in Dissimilar Welded Joint
Journal of the Japan Welding Society, 1963 The present study was carried out to make clear the C migration in dissimilar metal welded joint at high temperature. To prepare test pieces, C steel and 2 1/4 Cr-1 Mo steel plates were welded with eight kinds of ferritic electrodes, 1/2 Mo, Cr-Mo Cr-Mo-V etc.

Failure of a Dissimilar Metal Braze in an Expansion Joint [PDF]
Journal of Failure Analysis and Prevention, 2019 The failure of a hot water expansion joint in the heating system of a high-rise office building resulted in a catastrophic water leak. Brittle cracking occurred at a dissimilar braze joint between copper and stainless steel components. Failure analysis and instrumental characterization revealed that an incompatible phosphorus-containing, copper-based ...

Creep behavior and in-depth microstructural characterization of dissimilar joints
Science and Technology of Advanced Materials, 2013 The 700 °C power plants currently under development will utilize Ni-base alloys such as alloy 617 for components to be operated at temperatures >650 °C. Due to economic reasons for components or parts of components which are subjected to temperatures

Non-Destructive Testing of Dissimilar Welded Joints
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2021 This paper presents research’s results of non-destructive examination of dissimilar welded samples. The samples were made using sheets of austenitic stainless steel and carbon steel welded through the method of MAG welding with tubular wire. The samples were subjected to non-destructive testing in order to analyse the integrity of the welded seam, heat

Thermal autofrettage of dissimilar material brazed joints [PDF]
Materials & Design, 2015 This paper presents a study on the effects of thermal autofrettage on the residual stresses in a Titanium – Copper brazed joint. It is shown that cryogenic thermal autofrettage has the potential to alter the residual stress field due to joining, in a manner that should result in an improvement in the subsequent operational fatigue performance of ...
