Structure Property Correlation of Thin Wall Ductile Iron

Abstract

This research work concerns an assessment of the effect of one step inoculation method on thin section castings (2-5) mm analyzed. In this study inoculants representing Ce, Zr and Sr bearing Fe-Si alloys were used. It has been observed that section thickness of 2 mm thin plate containing Ce bearing Fe-Si alloys at 0.4wt% contain mainly pearlitic matrix having microhardness (HV20), ultimate tensile strength (UTS) and percentage of elongation are 272 HV, 720 MPa and 4.5% respectively. It was observed that wear of 2 mm section thickness of thin plate containing Ce bearing Fe-Si alloys have greater wear resistance (272HV) compare to Zr bearing Fe-Si alloys (262HV) and Sr bearing Fe-Si alloys (259HV) respectively at 0.4wt% due to reason of pearlitic and ferritic volume fraction contents present in matrix.

Analysis of Dissimilar Welding Joint between Inconel 718 and AISI 316L by GTAW Multipass Process

“…The technique of energy dispersive spectroscopy (EDS) was used to analyze the chemical composition of the FZ, being measured at several random points resulting in the average of the elements present. The variation of the chemical composition in each region of the welded sample was also determined by EDS, using in-line analysis, same method used in the studies by He et al [22], Upadhyaya and Singh [23] and Barnabas et al [24]. The HAZ close to AISI 316L (HAZ 316L), the FZ and the HAZ close to Inconel 718 (HAZ 718) of sample 2 were analyzed, as shown in Figure 4.…”
