Micromechanical investigations of CVD coated WC-Co cemented carbide by micropillar compression
(Elsevier, 2020-01-15)
Article
Accés obertDeformation behavior of an industrial coated cemented carbide (WC-Co substrate coated with CVD multilayer of TiN/Zr(C,N)/Ti(C,N,O)/Al2O3) was investigated by means of micropillar compression method. In addition to the WC-Co ... -
Micromechanical mapping of high entropy carbide based hardmetals
(2023)
Comunicació de congrés
Accés restringit per política de l'editorialHigh Entropy Alloys (HEA) are materials consisting of a mixture of five or more elements in equal or relatively large proportions. They are a promising alternative material due to their desirable properties such as good ... -
Microstructural effects on the fatigue crack nucleation in cold work tool steels
(2010-04)
Article
Accés restringit per política de l'editorialCrack nucleation mechanisms in two types of cold work tool steels were evaluated under monotonic and cyclic loading conditions. The effect of the microstructural constituents: the primary alloy carbides and the tempered ... -
Modelling of a charge control method for capacitive MEMS
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialCharging of dielectric materials in microelectromechanical systems (MEMS) actuated electrostatically is a major reliability issue. In our previous work we proposed a feedback loop control method that is implemented as ... -
