| description | Medium alloy steel is widely used as a material for guns and rocket launchers due to its high strength and excellent
machinability characteristics. The purpose of this study is to determine the material properties of the follower assembly
used in a breech block gun launcher which is significantly important f or the future product improvement. The
microstructure and the effect of alloying elements in the follower assembly is evaluated in this study. The SPECTRO
Optical Emission Spectroscopy (ES) method is used to analyse the chemical composition of the material and the Field
Emission Scanning Electron Microscope coupled with Energy Dispersive X-Ray (FESEM-EDX) were used to analyse
the inclusions of the sample. Results of the ES chemical composition analysis found that Nickel (Ni) is the major alloying
elements beside Molybdenum (Mo), Chromium (Cr), Manganese (Mn), Silicon (Si), Sulphur (S), and Carbon (C) while
chemical mapping and line scanning analysis of FESEM-EDX on inclusions distributed in the material microstructure
identified as a compound of Manganese Sulphur(MnS). Fine dendritic microstructure arrangement and distribution in
the microstructure analysis showed that the sample had been quenching in the heat treatment process, which also played
a significant role in the material characterization. From the analysis, it is found that the material can be defined as
medium alloy steel that is also typical for high strength material for ballistic application. |
