m was analyzed and each value
recorded was an average of 5 measurements. The microstructural
examination of the samples was done by using a
ZEISS optical microscope and JEOL JSM-6360LV scanning
electron microscope. An energy dispersive X-ray spectrometer
(EDX) system attached to the scanning electron microscope
was used to determine the chemical composition of the
phases present in the microstructure. The X-ray count rate
was estimated as 2× 103 counts per second (cps)
