EVALUATION OFDISLOCATION STRUCTURE AND CRYSTALLITE SIZE IN WORN AL-SI ALLOY BY X-RAY DIFFRACTION

Abstract: powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size anddislocation structures. In this paper the effect of the sliding on the microstructure of A356 in the as-cast and heattreated conditions are studied, The X-ray phase analysis shows that with increasing applied load, the dislocationdensity is increased, whereas the crysta...

Observation of X-ray transient XTE J1748−288 by the Indian X-ray astronomy experiment

The observations of a newly discovered X-ray transient source XTE J1748−288 were made in the energy band 2 − 18 keV with the Indian X-ray Astronomy Experiment(IXAE) on the IRS−P3 satellite during 1998, June 14−25. The source count rate declined gradually with an exponential decay time of 19 ± 1.6 days. The X-ray light curves showed no significant intensity variations on short time scales (≤ 10s...

X-ray Observation of Radio Supernova Sn1979c by Asca

We report on the X-ray observation of the radio selected supernova SN1979C carried out with ASCA in December 1997. The supernova of type IIL was first observed in the optical and occurred in the weakly barred, almost face on spiral galaxy NGC 4321 (M100) which is at a distance of 17.1 Mpc, and contains at least three other supernovae discovered in this century. No point source was detected at t...
