Micro-machinability of nanoparticle-reinforced Mg-based MMCs: an experimental investigation

Experimental Investigation into Micro Machinability of Mg based Metal Matrix Composites with nano-sized reinforcements

Magnesium based metal matrix composite (Mg/MMC) has been widely used in various area such as aerospace and automobile due to its light weight and better mechanical properties. However the heterogeneous structure and high abrasiveness particles make it to become a difficult-to-cut material especially in micro scale machining, several critical issues in machining process become prominent with the...

An experimental investigation on the machinability of powder formed silicon carbide particle reinforced aluminium metal matrix composites

The paper attempts to study the machinability issues of aluminium-silicon carbide (Al-SiC) metal matrix composites (MMC) in turning using HSS cutting tool. SiCp-reinforced metal matrix composites (MMCs) containing SiC particles (5wt%-20wt %) of 400mesh size were prepared by powder metallurgy (P/M) route and used as work material for turning. Experiments were conducted at various cutting speeds ...

Global Machinability of Al-Mg-Si Extrusions

Experimental Investigation of Mechanical and Thermal Properties of Silica Nanoparticle-Reinforced Poly(acrylamide) Nanocomposite Hydrogels

Current studies investigating properties of nanoparticle-reinforced polymers have shown that nanocomposites often exhibit improved properties compared to neat polymers. However, over two decades of research, using both experimental studies and modeling analyses, has not fully elucidated the mechanistic underpinnings behind these enhancements. Moreover, few studies have focused on developing an ...

Experimental Investigation of Behavior of Glass Fiber Reinforced Concrete (GFRC)

The paper presents the results of casting and testing of 264 GFRC specimens. The glass fibers were 25 mm long, with the aspect ratio (L/D) ranging between 1250 and 3570. The parameters studied were the ratio (by weight) of fibers to cement, i.e. F/C=0%, 1.5%, 3%, and 4.5%, and the ratio of coarse to fine aggregates (gravel to sand), i.e. G/S=1.1, 0.7 and 0.2. In total, 12 mix designs were selec...
