The ingot was found to be free from freckles, white spots, and ring pattern. It can be seen that the structure consists of only columnar grains oriented in an axial direction. Figure 5 shows the macrostructure of the ESR ingot. The microstructure of the steel in quenched and tempered condition consisted of tempered lath martensite as shown in Figure 6. The fractured surface of the tensile specimen was viewed under a scanning electron microscope to identify the mode of fracture. Figure 7 shows the presence of numerous dimples on the fracture surface which indicate it is ductile fracture and which have been formed by micro-void coalescence. ■ Fig. 7 Nanjiang Industrial Park,Sihui.Guangdong province.P.R.China.
