Determination of Elastic Constants in WC/Co Metal Matrix Composites by Resonant Ultrasound Spectroscopy (RUS) and Impulse Excitation

Simulation on the Effect of Porosity in the Elastic Modulus of SiC Particle Reinforced Al Matrix Composites

“…Square and circular morphologies of the particle reinforcement were selected to elucidate the effect of the inclusion shape in the elastic moduli. Two validation studies are conducted first by comparing the FEA results within experimental data reported for the system Co-WC [25] and experimental results for porous refractory spinel [16]. In the case of matrix strengthening, the composite matrix is made of cobalt (Co), whose elastic modulus E 2 = 207 [GPa], Poisson's ratio η 2 = 0.31 and shear modulus G 2 = 79 [GPa].…”

“…The inclusion is tungsten carbide (WC) whose elastic modulus E 1 = 700 [GPa], Poisson's ratio η 1 = 0.23, and shear modulus G 1 = 278 [GPa]. For the Co-WC composite, experimental data of the elastic moduli as a function of the volume fraction of reinforcement ranging at high concentrations of filler are available in the literature [25]. Therefore, this data allows examining the reliability of the numerical model when high volume fractions are considered.…”

In situ synthesis of WC–Co nanocomposite powder via core–shell structure formation

“…With inimitable properties, such as excellent wear resistance, high hardness and toughness, WC-Co has been widely used in military, aerospace, automotive, electronics, mining and machining [1][2][3]. Furthermore, the hardness and the strength of cemented carbides increase remarkably when the grain size is reduced to a range of nanometer, as well as the toughness improves greatly [4][5][6][7].…”

Modeling the Influence of Orientation Texture on the Strength of WC–Co Composites

“…OOF has been used to study thermal expansion‐induced spontaneous microcracking in alumina 7 . The OOF package has also been used to calculate Young's moduli and thermal expansion coefficients of silicon carbide–aluminum (SiC–Al) and double carbide (WC–Co) composites 8–10 . More advanced models have recently been used to calculate the mechanical properties of metal–ceramic composites, but crystallographic properties have not been incorporated into these simulations 11–12 …”

“…7 The OOF package has also been used to calculate Young's moduli and thermal expansion coefficients of silicon carbide-aluminum (SiC-Al) and double carbide (WC-Co) composites. [8][9][10] More advanced models have recently been used to calculate the mechanical properties of metal-ceramic composites, but crystallographic properties have not been incorporated into these simulations. [11][12] The methods used in the present paper to simulate the residual stresses and strengths of textured WC-Co composites have already been described in detail.…”
