Item Experimental data on mechanical properties evaluation of medium carbon steel quenched in different waste media(Elsevier, 2018-09-05) T.S. Olabamiji; C.O. Osueke; B.T. Ogunsemi; Adekunle Akanni Adeleke; D.C. Uguru-Okorie; Adeolu Adesoji Adediran; Peter Pelumi Ikubanni; O.O. AgboolaSeveral wastes can be instrumental in the improvement of the mechanical properties of medium carbon steel when quenched. The quenching media employed such as coconut water (CW), pap water (PW) and spent engine oil (SPE) have been largely considered as wastes. The data in this article are related to the research article titled "Mechanical Properties Improvement Evaluation of Medium Carbon Steels Quenched in Different Media" (Ikubanni et al., 2017) [1]. The article provides information on the mechanical properties evaluation of medium carbon steel quenched in different media. Twenty-seven (27) samples of medium carbon steel samples were heated to temperatures of 730 °C, 760 °C and 790 °C and soaked for 30, 45 and 60 min respectively. The test results recorded include hardness value, yield strength (YS) and the ultimate tensile strength (UTS) for each of the samples at different heating temperatures and soaking time for the different quenching media.Item Fabrication and Evaluation of Screw-like Fish Pelletizer(IOP Publishing, 2019-12-18) Peter Pelumi Ikubanni; O.O. Agboola; B.T. Ogunsemi; Adekunle Akanni Adeleke; R.A. IbikunleGood and balanced meals are required for fish to stay healthy and the production of these meals requires some machines like pelletizer. This study therefore contributes to the improvement of existing models of this machine by designing, fabricating and evaluating the performance of a new pelletizer. After fabrication, 5 kg fish feed ingredients weight was processed for 2.5 minutes in the machine in quadruplicate. The average discharge efficiency, percentage loss due to residue ingredients and production rate for the machine are 92.25 %, 7.75 % and 110.7 kg/h, respectively. The results showed that an increase in drying days led to a corresponding increase in percentage moisture content removal with a similar reduction in the weight of the pelletized fish meal. This machine will be of great assistant to medium and small-scale aquaculture farmers, thereby reducing the need for foreign sources of fish feed in fish farming sector.Item Comparative Analysis of Manual Strapping Method (MSM) and Electro-Optical Distance Ranging (EODR) Method of Tank Calibration(IOP Publishing, 2019-12-18) O.O. Agboola; B.O. Akinnuli; M. A. Akintunde; Peter Pelumi Ikubanni; Adekunle Akanni AdelekeOil storage tanks are mandated for calibration before putting to use and to be recalibrated as a statutory requirement at every five year interval. Oil tanks could be calibrated by geometrical methods such as Manual Strapping Method (MSM) and Electro-Optical Distance Ranging (EODR) method. This study compares both MSM and EODR in terms of cost incurred, duration of calibration and efficiency. Both methods were found to be efficient as they satisfied 95% minimum efficiency as stated by API MPMS 2.2 standard when compared with the wet method of tank calibration; though the cost of EODR was slightly higher than MSM but this was compensated with higher efficiency and reduced duration/time of calibrationItem Physico-Mechanical Properties of Particleboards Produced from Locally Sourced Materials(Trans Tech Publications, 2018-11-08) Peter Pelumi Ikubanni; Adekunle Akanni Adeleke; Adeolu Adesoji Adediran; O.O. AgboolaIn this study, particleboard was produced from the blend of sawdust and rice husk with the inclusion of metallic chips and adhesives. Urea formaldehyde and gelatinous starch were used as adhesives. Particleboards (10 mm thickness) were made from varying weight percentage ratio of saw dust and rice husk using pressure in the neighbourhood of 3 N/mm2 . The particleboard was tested to determine the density, modulus of rupture (MOR), modulus of elasticity (MOE) and internal bonding strength (IBS). The density of the particleboards developed varies from 762.86 to 801.60 kg/m3 . The moisture content of the samples varied between 9.22% and 9.98%. The MOR, MOE and IB values varied between 5.08 MPa and 26.08 MPa; 75.38 MPa and 412.4 MPa; and 0.013 MPa to 0.07 MPa, respectively. Composite samples C, E and H values for MOR, MOE and IBS gave significant results which met with the EN, ANSI A 208.1 and USDA standards. Hence, the admixture of rice husk and sawdust together with UF adhesive will be suitable in producing particleboard that could be useful for indoor and outdoor purposes.Item Microstructural assessment of AISI 1021 steel under rapid cyclic heat treatment process(Elsevier, 2019-10-13) Adekunle Akanni Adeleke; Peter Pelumi Ikubanni; T. A. Orhadahwe; J.O. Aweda; Jamiu Kolawole Odusote; O.O. AgboolaThis research was aimed at using image analysis to describe the effects of rapid cyclic heating on mild steel. AISI 1021 steel sample used in this study was subjected to quenching heat treatment followed by 1, 2, 3, and 4-cycles of rapid heat treatment. The as-treated steel samples were characterized by Brinell hardness tests, Charpy V-notch impact tests, optical microscopy, and image analysis using Image J software. The results revealed that the grain size decreased from 1.07 μm in the control sample to 0.79 μm in the third cycle sample and increased to 0.86 μm in the fourth cycle sample. However, the results revealed that two-cycles of rapid heat treatment was enough to produce ultra-fine grains and impact ductility in mild carbon steel.

Odusote; Peter Pelumi Ikubanni; O.A. Lasode; O.O. Agboola; A. Ammasi; K.R. AjaoThe quality of steel rods used in structural applications has been subjected to continuous scrutiny by researchers in Nigeria. In this data article, the experimental data on the chemical and mechanical properties of steel rods from collapsed building sites and local steel plants have been reported. The chemical composition consisting of carbon, manganese, silicon, sulphur, phosphorus among other elements were recorded using an optical emission spectrometer. Some of the main elements were used to evaluate the carbon equivalent value and the results are reported in this article. The yield strength, ultimate tensile strength and percentage elongation were also presented as obtained from the universal testing machine. The hardness values of the steel rod samples were also presented
