In this work, TiC/M2 high speed steel metal matrix composites (MMCs) were prepared using the ball milling method and laser powder bed fusing process. By controlling TiC content in TiC/M2HSS, grain size, phase composition, frictional wear properties of samples enhanced. The results showed that when TiC/M2HSS was supplemented with 1% TiC, surface microhardness increased to a maximum value volume ...

surements can be performed at much reduced exposure times THE load-bearing capacity of a metal matrix composite and in small diffracting volumes, thus allowing for investi(MMC) is dictated by the load transfer occurring from the gating the time dependenceof lattice strains and for mapping compliant, soft matrix to the stiff, hard reinforcements. such strains with a lateral resolution of a fract...

Pleomorphic adenomas with a nuclear palisading arrangement of spindle-shaped modified myoepithelial cells (MMCs), suggesting the appearance of palisading leiomyoma or Antoni's A type of neurilemmoma, are quite rare, and its cytologic nature has been poorly understood. This paper reports histologic and immunohistochemical findings of palisading MMCs in two cases of pleomorphic adenoma. Histologi...

The mechanical and morphological properties of the unidirectional metal matrix composite (MMC) in titanium alloy reinforced with continuous silicon carbide (SiC) fibres are investigated. lay-up manufacturing process known as Foil / Fibre (FF) was compared matrix-coated-fibre (CF) method which promises a better final shape reinforcing fibre net. Tensile tests were performed to measure performanc...

In this experimental study, three TiB2/Al metal matrix composites (MMCs) with 40 μm in mean size were produced using a melt stirring squeeze casting route. Test was carried out to find the parameters influencing surface roughness (Ra) and material removal rate (MRR) on machining the TiB2 reinforced Al-6063 composite materials. The orthogonal array, the signal-to-noise ratio, and analysis of var...

Magnesium metal matrix composites (Mg MMCs) possess relatively more favorable mechanical properties than Mg alloys because they add reinforcements, such as small particles, short fibers, or continuous fibers, into the matrix. This study investigated the influence of adding different sizes and percentages of silicon carbide particles (SiCp) for manufacturing AZ61/SiCp Mg alloy composite extrusio...

the use of methods employed for estimating the strength and toughness of composites reduces the trial-and-error in their design. the strength of interface between reinforcement and matrix and the effective surface of pulled-out particles have great influences on toughness and strength of these composites. in this study, a model was proposed to estimate the interface strength and matrix strength...

combustion synthesis has been used to produce fe-(ti,w)c composites. a simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. samples with different w/ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. different composites such as wc in fe-ti matrix, wc+(ti,w)c in fe matrix...
