Mechanical properties and tribological behavior of aluminum matrix composites reinforced with in-situ AlB2 particles AbstractAluminum matrix composites (AMCs) reinforced with in-situ AlB 2 particles have been fabricated using a combination of powder metallurgy, hot rolling and solution treatment. The effects of boron content (7 and 12 wt%), hot rolling and heat treatment parameters on the microstructures and mechanical properties of the composites were investigated by means of scanning electron microscopy (SEM), tensile test and microhardness measurements. The friction coefficient, wear behavior and scratch morphology of the AMCs and pure aluminum were also studied using scratch tests. The hardness and wear properties are higher in a case of composites when compared to unreinforced matrix material.

E-mail address: hanjt@ustb.edu.cn(Jingtao Han) 1. Introduction Aluminum matrix composites(AMCs) reinforced with ceramic particles have been extensively used in the aircraft, aerospace and automotive industries because of their high stiffness, strength to weight ratio, low coefficient of thermal expansion and good wear resistance [1][2][3]. The particulate reinforcements most often added to the pure aluminum or alloys include SiC, SiO2, B4C, TiB2 and Al2O3 [4][5][6][7][8][9]. In previous studies, Khorshid et al. prepared the AMCs reinforced by two sizes of alumina particles by wet attrition milling and hot forward extrusion processes [10]. Haghighi et al. consolidated Al-5 vol.% nano-Al2O3 by equal channel angular pressing and extrusion and compared the physical and mechanical properties [11]. Vajargah et al. fabricated Al/TiB2 nano composites via powder metallurgy route through a primarily...

“…The mass measurements, accurate to 0.01 mg, were made on a digital electronic analytical balance (Mettler, AG 285, Switzerland). The total uncertainty of the density is 3 × 10 −4 g · cm −3 , and that of the temperature is 0.01 K. The viscosity was measured by means of a suspended Ubbelohde type viscometer [14], which was calibrated at 298.15 K with triple-distilled water and purified methanol using density and viscosity values from the literature [7,11,15]. The flow times were accurate to ±0.1 s, and the uncertainty in the viscosity measurements is 2 × 10 −4 mPa · s. Speeds of sound were determined by a multifrequency ultrasonic interferometer (Mittal Enterprise, New Delhi) operating at 5 MHz, calibrated with water, methanol, and benzene at 298.15 K [11,15].…”

Densities and viscosities were measured for the binary mixtures of cyclohexylamine and cyclohexanone with butyl acetate, butanone, butylamine, tertbutylamine, and 2-butoxyethanol at 298.15 K over the entire composition range. From density data, the values of the excess molar volume (V E ) have been calculated. The experimental viscosity data were correlated by means of the equation of GrunbergNissan. The density and viscosity data have been analyzed in terms of some semiempirical viscosity models. The results are discussed in terms of molecular interactions and structural effects. The excess molar volume is found to be either negative or positive depending on the molecular interactions and the nature of the liquid mixtures and is discussed in terms of molecular interactions and structural changes.

“…Recently, many authors [13][14][15][16][17][18] have continued to predict molecular interactions from the deviations calculated using mole fraction or volume fraction averages rather than using the correct equations described herein.…”
