Abstract |
The suitability of date-seed/snail shells as a carburizer for enhanced mechanical properties of mild-steel
using the packed carburization technique was investigated in this work. Standard tensile, impact and hardness test
samples prepared from mild-steel were subjected to pack-carburization process using mixtures of date-seed and snail
shell in the ratio 60:40 respectively at 800, 900, and 1 000 °C for 3 hours. The carburized samples were quenched in
water at room temperature and further tempered at 300 °C for 30 minutes for residual stress relief of the quenching
effect. The mechanical properties and optical microstructure of carburized specimen were performed. Results indicated
an enhanced mechanical property of the carburized mild-steel using date-steel/snail shell as a carburizer compared to
un-carburized same steel material. The tensile strength and hardness increased with increasing carburizing temperature,
though with an associated decrease in ductility. The peak hardness (32.82 HRB) and tensile strength (521 MPa) with
equivalent 31.28 and 51.45 percentage increments respectively were obtained at carburizing temperature of 1 000 °C.
Hence, using date-seed/snail shell powder as a carburizer can enhance the mechanical properties of mild-steel. |
