Cyclic loading of WC-Ni by FEM with a realistic 3D morphology

Daniele Mari, Lucas Eric Jacques Degeneve

A Finite Element Model produced from a real WC-10wt.%Co sample is used to study the mechanical behavior of cemented carbides in compression tests. The model is obtained by slicing the sample by Focused Ion Beam and reconstructing it. This model is used to ...

Using mechanical spectroscopy in order to study the thermodynamics of a strain glass in a WC–Co ceramic metal composite

Daniele Mari, Lucas Eric Jacques Degeneve

WC–Co cemented carbides are one of the most widely used materials for the production of cutting tools, for their exceptional mechanical properties. Due to the extreme mechanical and thermal conditions of the cutting operations, understanding and controllin ...

Study of Faraday waves in tanks in presence of polystyrene bead layers

Daniele Mari

When a tank is subjected to vertical forced excitation, Faraday waves appear at the surface of the liquid the tank contains. In this paper, we consider the effect of layers of polystyrene beads placed on the surface of isopropanol undergoing a low frequenc ...

Distribution of the thermal residual stresses in the WC-Co microstructure by finite element method

Daniele Mari, Lucas Eric Jacques Degeneve

A Finite Element Model is used to observe the build-up of residual thermal stresses during the sintering process in two WC-Co samples with different volume fractions of Co. A realistic model of the two phase material is obtained by FIB slicing a real WC-Co ...

Relaxation time shift of Cobalt related internal friction peak in WC-Co cemented carbide

Daniele Mari, Samy Adjam, Lucas Eric Jacques Degeneve

Cemented carbides are widely used in the cutting tools industry for their mechanical properties. They are composite materials made of hard tungsten carbide grains jointed together by a ductile cobalt binder. Due to the extreme conditions of use of the tool ...

FEM of stress partition during compression of WC-10 wt.% Co with realistic 3D morphology

Daniele Mari, Lucas Eric Jacques Degeneve

A Finite Element Model is developed to represent the mechanical behavior of WC-10 wt.% Co in compression tests. In this research, realistic three-dimensional model is obtained by slicing a sample by Focused Ion Beam and reconstituting it, resulting in two ...

Strain glass transition of cobalt phase in a cemented carbide

Daniele Mari, Thomas La Grange, Samy Adjam

Cemented carbides are hard materials used for the fabrication of cutting tools. They consist of hard micron or sub-micron carbide grains held together in a matrix of a tough metallic binder such as cobalt. The understanding and control of cobalt characteri ...

In situ X-ray diffraction and the internal friction study of the binary yellow 18-carat gold alloy

Daniele Mari

Phase transitions in AuCu alloy are investigated using in situ temperature XRD and mechanical spectroscopy. The measurements are carried out from room temperature up to 973 K starting from the ordered phase AuCuI. Using a temperature ramp rate of 1 K/min, ...

Mechanical spectroscopy as an in situ tool to study first and second order transitions in metastable Fe-Ga alloys

Daniele Mari

Phase transitions and related anelastic effects are examined in Fe-xGa alloys (x =19 and 27 at.%) by means of in situ neutron diffraction, vibrating sample magnetometry, dilatometry, and three different mechanical spectroscopy techniques: torsion forced pe ...

The Contribution of Mechanical Spectroscopy to Understanding Grain Boundary Sliding

Daniele Mari

This review paper shows that grain boundary sliding (GBS) is a general phenomenon occurring in all classes of inorganic materials: ceramics, metals and composite materials. The occurrence of relaxations attributed to GBS is also quite general and therefore ...

Secondary hardening in Co-Ni-Cr super-alloy investigated by Mechanical Spectroscopy

Daniele Mari, Raffaele Cosimati

The effects of thermal treatments on a Co-Ni-Cr super-alloy in the temperature range from 250 degrees C to 900 degrees C, resulting in secondary hardening, have been studied by Mechanical Spectroscopy. The simultaneous evolution of the internal friction sp ...
