One step synthesis of dense MoSi2–SiC composite by high-frequency induction heated combustion and its mechanical properties

Rapid consolidation of nanocrystalline Al2O3 reinforced Ni–Fe composite from mechanically alloyed powders by high frequency induction heated sintering

“…Indentations with large enough loads produced median cracks around the indent. The length of these cracks permits an estimation of the fracture toughness of the material by Niihara et al expression [18,19]. where c is the trace length of the crack measured from the center of the indentation, a the half of average length of two indent diagonals, and H v the hardness.…”

In-situ synthesis of MoSi2 coating on molybdenum substrate by electro-deoxidation of a SiO2 layer in molten salt

“…MoSi 2 has received considerable attention as a material for hightemperature applications due to its high melting point of 2030 1C, moderate density of 6.24 g/cm 3 , high modulus (440 GPA), as well as excellent resistance to oxidation (up to 1700 1C) [1,2]. In particular, it has been regarded as an attractive coating material for protection of Mo and Mo-based alloys used in oxidative atmospheres at high temperatures [3,4].…”

Microstructures and Mechanical Properties of Hot-Pressed -Matrix Composites Reinforced with SiC and Particles

“…However, as in the case of many such compounds, the current concern about these materials focuses on their low fracture toughness below the ductile-brittle transition temperature [5,6]. To improve the mechanical properties of these materials, the addition of a second phase to form composites [7][8][9][10] has been found to be effective. Silicon nitride (Si 3 N 4 ) has a high thermal shock resistance, due to its low thermal expansion coefficient and good resistance to oxidation when compared to other structural materials [11][12][13].…”
