The aim.of this research was to exam.ne the effect of m.crostructural param.ters on the tensile properties of different com.ositions of tungsten heavy alloys. The m.crostructural param.ters （grain size, connectivity, contiguity, and solid volum. fraction） were m.asured and were found to have a significant effect on the tensile properties of tungsten-based heavy alloys. The m.crostructural param.ters of W-Ni-Fe alloys are sufficiently different to present a range of m.chanical properties. It is concluded that the m.chanical properties of tungsten heavy alloys largely depend on the m.crostructural param.ters and their ductility is particularly harm.d when grains are contiguous.

Using a statistical m.thod which is based on random.m.trix theory, the results for the nearest-neighbor energy spacing distributions E(S) obtained from.experim.ntal as well as from.com.utational data have been selected for review study. The obtained results confirm.that the energy spacing correlation between secondary charged particles depends upon the charged particles m.ltiplicity and central collisions are also associated with charged particles m.ltiplicity.

A therm.plastic based com.osite m.terial is suitable for autom.bile and aerospace applications. The recyclability of therm.plastic and clean processing further enhance its use. The only lim.tation encountered in using this m.terial is its high-m.lt viscosity. Various techniques have been developed to overcom. this problem. Com.ingled m.terials are one of such m.thods adopted for m.king proper use of therm.plastic. A m.jor problem.observed during the use of a com.ingled m.terial is its de-com.ingling, wherein, the uniform.distribution of fiber and therm.plastic yam.gets disturbed and affects the final quality of the com.osite. The effects of the braiding process on lam.nate quality were investigated. Flat plaques were produced by braiding the com.ingled yam. using a 48- carrier braiding m.chine. The braids （and control woven sam.les） were subsequently heated and consolidated in a nonisotherm.l com.ression m.lding operation. Prior to the m.nufacture of the ＇best quality＇ plaques, a series of m.ldings were produced under different consolidation conditions, to study the dependence of properties on the process variables. This enabled a processing window to be established for each m.terial and helped to separate the respective effects of yam.handling, textile processing, and consolidation on lam.nate properties.

A system.tic analysis of the data on 14.5A GeV/c 28Si-nucleus collisions is carried out to investigate the behaviours of Renyi dim.nsions, Dq and m.ltifractal Spectral Function, f(αq). The Renyi dim.nsions, Dq are observed to decrease with increasing order of the m.m.nts, q. However, the m.ltifractal Spectra are concave downwards with their m.xim. occurring around αq =1.21±0.01. A continuous curve representing m.ltifractal Spectral Function, f(αq), characterizes m.nifestation of fluctuations in the rapidity space.
