X-Ray Diffraction and Microstructure Analysis of EN47 Spring Steel at Various Soaking Period of Time

The study presents the results of the investigation on the effect of soaking time on the, Crystalline structure and morphological properties of annealed EN-47 Spring Steel. The EN-47 Spring Steel samples were heated at 860 °C for soaking times of 60, 120, 240, 480 minutes. SEM analysis and XRD analysis were carried out to determine the morphology and crystalline phase of the material with increasing soaking time. Interatomic Distances also decreased with increased in soaking time. The sample with the Soaking time of 480 minutes exhibits a higher Interatomic Distance because of Formation of bigger grains. Through X-ray Diffraction transformation of the crystalline structure were analyzed, in that it is observed that Iron did not undergo any crystalline structure transformation with respect to soaking time whereas other elements changed their structure.
