A review of Al based metal matrix composite reinforced with TiB2 particles developed after 1997 is presented in this paper. This paper presents an overview of Al-TiB2 MMC on aspects relating to the ...formation of TiB2, development of Al-TiB2, mechanical characteristics, thermodynamic calculation, wear behavior of Al-TiB2, cycle fatigue response of insitu Al based composite, processing, microstructure, properties and application are discussed. Aluminium alloys are widely used for commercial applications in the transportation, construction and similar engineering industries. Nowadays, main focus is given to Aluminium as matrix material because of its unique combination of good corrosion resistance, low electrical resistance and it possesses excellent mechanical properties in addition to good corrosion resistance due to which the alloy finds extensive application in naval vessels manufacturing. Al-TiB2 composite is a metal matrix composite (MMC) that can be manufactured using the in-situ salt-metal reaction. With TiB2 as the particulate addition the properties of Al 6061 alloy can be greatly improved. The addition of TiB2 to aluminium increases the strength of the aluminium. The wear resistance of this material is due to the lack of pull out of this material from the aluminium matix. Also, such material when machine with non–conventional methods like EDM will show better machinability due to its high conductivity. In the last few years, Al-TiB2 have been utilized in high-tech structural and functional applications including aerospace, defense, automotive, and thermal management areas, as well as in sports and recreation. The future research is summarized finally.
The computer package
FLUIDS contains five sets of computer programs written in C++ for the calculation of fluid properties. Both model fluids and data from fluid inclusions can be analysed in the ...programs. Bulk density, molar volume and composition of fluid inclusions are calculated with the program
BULK, which uses microthermometric data, micro-Raman spectroscopic data, cation ratios and volume-fraction estimations as input. The program offers a broad variety of equations of state, which are selected according to the fluid system or the temperature and pressure conditions of interest. The isochores that correspond to the output or test
V−
x properties of fluid inclusions are calculated by the program
ISOC. In calculating the isochores, this program takes account of the compressibility and expansion of selected host minerals. The program
TEST allows different equations of state to be compared directly with experimental data, thereby facilitating selection of the most adequate model in the programs
BULK and
ISOC.
Loner is a group of programs that handle individual equations of state (EoS) for all fluid systems presented in the programs
BULK and
ISOC.
Aqso is a group of programs that allows purely empirical modelling of electrolyte-bearing aqueous solutions, Henry's law for dilute gas-bearing aqueous solutions, and osmotic coefficients for dilute electrolyte-bearing aqueous solutions. The programs are available on the University of Leoben web site at
