The use of dissimilar materials is increasing exponentially in the automotive industry due to possibility achieving weight reduction from multi-material design. Friction Element Welding (FEW) an advanced solid-state joining technique employed for using a friction element. processing time FEW relatively higher than few its competitive techniques, with cleaning step contributing majority time. cu...

Synthesis of BaFe12O19 magnetic nano particles via precipitation in different pH conditions have been reported. The certain molar ratio of Fe/Ba = 12 selected and sodium hydroxide was used as a precipitant agent. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and vibrating sample magnetometer (VSM) were used to consider the structural, morphological and magnetic properties of bariu...

Wood processing industries have continuously developed and improved technologies and processes to transform wood to obtain better final product quality and thus increase profits. Abrasive machining is one of the most important of these processes and therefore merits special attention and study. The objective of this work was to evaluate and demonstrate a process monitoring system for use in the...

274 Optimization of process parameter for surface finishing in abrasive flow finishing process Ravi Gupta (M.E) Asst. Prof.(Lovely Professional University) [email protected] , Abstract-Abrasive flow finishing is a non-conventional finishing process that is used for finishing of work piece which are difficult to finish by conventional method i.e. by honing, lapping and other machining operati...

using a magnetic property measurement system (mpms), we measure magnetic susceptibility continuously at frequencies from 0 to 1000 hz for three different superparamagnetic (sp) grain sizes of magnetite (5nm, 7 nm and 10 nm) suspended in hydrocarbons (ferrofluids). our results confirm non-zero values of frequency-dependent susceptibility in the fine tail of nano-sized grains and provide new empi...

gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. high specific impulse, good density and safety better than that of both solid and liquid propellants are advantages of the gel propellants. they are made by addition a suitable gellant to liquid propellants. in this research, nano al particles have been used in udmh gel fuel. the gel...
