ABSTRACT
The research evaluates the chemical, mechanical and microstructural characterization of an armour
steel sourced from a scraped armoured vehicle in order to develop local content in the armouring
technology. Chemical analysis, optical microscopy and mechanical tests were employed to
examine the microstructural and mechanical properties of a low carbon armour steel. Chemical
analysis showed the elemental constituents and the exact weight per percentage of each element
present in the test sample as per MIL-DTL-12560J standards. Microstructural analysis was carried
out on etched sample of the plate which exhibited the desired bainitic microstructure. Dispersed
within the bainitic microstructure were high carbon micro constituents consisting of iron carbides
and pearlite. Then hardness, tensile and impact strength of the plate were assessed following
standard procedures. The results showed that the specimen tested has a tensile strength of
1291MPa, a hardness value of 479BHN, 11 % elongation, and impact resistance of 27. lSJ. The
mechanical performance of the plate was in consonance with the minimum mechanical
requirements of MIL-DTL-12560J standards. This study, therefore established that the tested armour steel plate is effective for high impact performance.
