The intrinsic hardness of the constitutive phases in WC Co composites is investigated by combining experimental and statistical analysis nanoindentation techniques.
This combined analysis elucidates the partitioning of stress and strain between the different constitutive phases.
The detailed formulation and validation of a phase size distributions for the three constitutive phases, as well as resistive loss microstructure-induced resistive loss distributions in the nickel (Ni) and yttria-stabilized zirconia (YSZ) phases are provided in this section.
X-ray Photoelectron Spectroscopy (XPS) and Raman spectroscopy techniques showed the presence of phosphor compounds and anatase (TiO2) as the main constitutive phases.
This paper presents an identification procedure based on the Virtual Fields Method (VFM) for identifying in situ mechanical properties of composite materials constitutive phases from 3D full-field measurements.
Finally, the results are analyzed and compared with data from the literature in terms of volume fraction and chemical composition of the constitutive phases.
An understanding of the overall nanocomposite behaviour is developed through the combination of real data from micro/nanostructures and the fundamental material characteristics of the constitutive phases.
The morphological structure of the hybrids was examined by TEM, SAXS and WAXS analysis, and confirmation of the identified co-continuity of the constitutive phases for nominal silica contents greater than 18%wt was obtained by TGA and DMA analysis.
For this purpose, the values of Vickers microhardness on the surface of specimens for different constitutive phases, ferrite and pearlite, are measured under different stress amplitudes during the fatigue damage process and their distribution characteristics are further examined.
