in this research, effects of concentration and time of silane treatment of rice straw flour on the morphology and mechanical strengths of rice straw flour/polypropylene composites were investigated. tri ethoxy vinyl silane (c8h18o3si) with 98% purity in two concentrations of 5 and 10%, that each concentration had two immersion times including, 45 and 90 min for using treatment rice straw flour....

This study investigates the wear resistance of four AA6061 MMCs together with the monolithic AA6061 alloy, all in the T6 condition, using a pin-on-disc test. In addition to the widely studied 20 vol.% Saffil MMCs, the present investigation considered a hybrid of 11% Saffil + 20% Sic, and a high volume fraction Sic, MMC. AA6061 + 60% Sic,. The wear behaviour against P400 Sic grit adhesive bonded...

The microstructure and wear behavior of S390 high-speed steel (HSS) reinforced with different volume fractions MC-type carbides produced via spark plasma sintering were investigated using scanning electron microscopy (SEM) transmission (TEM) in this study. SEM TEM results show that V-W-rich are formed around the added carbides, these have a similar composition to M(C, N) precipitated at high te...

In the present work, microstructure and mechanical properties of microwave welded Al6061-6%Graphite-SiC hybrid metal matrix composites (MMC) were investigated. The welding was carried out using principle heating Al6061 powder as an interfacial material. domestic oven having frequency 2.45 GHz 900 W power used for experiments. charcoal a susceptor during process. MMCs Al6061-6%Gr-SiC developed t...

Due to its exceptional mechanical characteristics combined with lightweight and fuel-efficient materials, metal matrix composites (MMCs) have largely been developed for the automotive aerospace industries. In this paper, an attempt was made investigate dry sliding wear behavior of aluminium-based hybrid MMC's through experimental approach. The experiments were performed three types filler mater...

Abrasive flow machining (AFM) is one of the non-conventional finishing processes used to attain good surface quality and high material removal. However, limited attempts have been made improve performance these processes. This paper presents a novel magnetic abrasive (MAFM) setup fabricated by adding magnetization effect in which nylon fixture permanent magnets are replaced newly aluminium coil...

automotive and aerospace industries are required to light materials which have high properties. this causes to reduce production cost and fuel consumption. one of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. these materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. powder metal...

The development of many engineered product applications for automobiles and aircraft parts has initiated the search novel materials as alternatives to metal matrix composites (MMCs). Natural-fiber-reinforced polymer offer distinct advantages such biodegradability, eco-friendliness, flexibility, low density, higher specific strengths, etc. This study focuses on natural-fiber (hemp banana)-fabric...

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...
