“…The price of silicon carbide is lower than that of boron carbide and ballistic performance of silicon carbide is very close to that of boron carbide. Thus many researchers have worked for production of armor system with as low boron carbide content as possible [5]. Silicon carbide is often mixed with boron carbide, but monolithic silicon carbide is also used in production of armor materials.…”

This paper discuss the effect of processing details such as particle size, sintering temperature, preform preparation, aluminum alloy characteristics and melt temperature on the final mechanical properties of ceramic phase reinforced metal matrix composites. Since alloy composition was determined as 7075 and 7085 optimum solutionizing and ageing temperatures were studied to determine maximum hardness values. For only 7085 alloy best solutionizing temperature is 465°C and for 7075 alloy the maximum hardness achived as 178 BHN after heat treatment at 475°C. Alloys were heat treated for recystallization after hot rolling grain size were measured as 100-120 µm for 7085 alloy matrix.Various sintering temperatures were used for preform preparation such as 1300-1450°C. In 85% Al 2 O 3 reinforced 7085 Alloy based MMCs preforms sintered at 1450°C high hardness values were achieved as 545 BHN. Intermetallic phase was determined in 7075 and 7085 alloys selected as alloy matrix. Al 2 Cu intermetallic pecipitate (θ phase) was determined as dominant second phase after T6 heat treatment but highly expected phase in 7000 series alloys MgZn 2 (η phase) was not determined by XRD and SEM analysis techniques due to ultrafine precipitate size and homogeneous distribution.

“…The most important criteria of melt infiltration process are the wetting behavior of the system. Wettability is the ability of a liquid to spread on a solid surface and it demonstrates the extent of close contact between a liquid and a solid [5]. The driving force for wetting is the reduction in free energy of the system.…”

“…Arslan and Kalemtas [7] reported that the reaction of Al and B 4 C formed two or three phase's composition such as Al 3 BC, AlB 10 and Al 4 C 3 where Al 3 BC phase was most observed. Processing at high temperature will produce unwanted composition such as Al 4 BC AlB 24 C 4 and Al 4 C 3 [7,8].…”

“…Processing at high temperature will produce unwanted composition such as Al 4 BC AlB 24 C 4 and Al 4 C 3 [7,8]. This composition will cause the deterioration of the structure and mechanical properties of the composites and more complicated phases developed at temperature greater than 900 o C [7,8].…”

Abstract. Al-Si-Mg-B4C composites containing 2-8 wt% of B4C were prepared by stir casting technique. Homogenization treatment was carried out at temperatures of 540 o C for 4 houra and followed by ageing at 180 o C for 2 houra. Microstructure and phase identification were studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. Neutron absorption study was investigated using neutron source Am/Be 241 . The result indicated that higher B4C content improved the neutron absorption property. Meanwhile homogeneity of the composite was increased by ageing processes. This composite is potential to be used as neutron shielding material especially for nuclear reactor application.

“…[9][10][11][12][13][14] Because B 4 C is very reactive with molten Al [15] and thus it meets the required wetting condition, it is feasible to use the pressureless infiltration method to prepare the B 4 C/Al MMCs. [16][17][18][19][20][21] In the literature, as compared with other systems like SiC/Al, the information is limited concerning the B 4 C/ Al MMCs. Viala et al systematically studied the chemical reactivity of B 4 C with Al.…”

In this work, B 4 C particulate-reinforced Al composite was fabricated by a pressureless infiltration technique, and its interfacial microstructure was studied in detail by X-ray diffraction as well as by scanning and transmission electron microscopy. The B 4 C phase was unstable in Al melt during the infiltration process, forming AlB 10 -type AlB 24 C 4 or Al 2.1 B 51 C 8 as a major reactant phase. The Al matrix was large grains (over 10 lm), which had no definite orientation relationships (ORs) with the randomly orientated B 4 C or its reactant particles, except for possible nucleation sites with f011g B 4 C almost parallel to {111} Al at a deviation angle of 1.5 deg. Both B 4 C-Al and reactant-Al interfaces are semicoherent and free of other phases. A comparison was made with the SiC/Al composite fabricated similarly by the pressureless infiltration. It was suggested that the lack of ORs between the Al matrix and reinforced particles, except for possible nucleation sites, is the common feature of the composites prepared by the infiltration method.
