Earing characteristics of cold-rolled and temper annealed aluminium 1200
(Asian Network for Scientific Information, 2006) Aderibigbe, D. A.; Oluwole, O. O.; Olorunniwo, O. E.; Atanda, P. O.; Ogundare, O.
Earing characteristics of deep-drawn cold-rooled and temper-annealed 1200 was studied at high deformation levels of 75,85,and 90% cold rolling. The relationshp of earing with varying degrees of cold roll was studied and the effect of different annealing temperatures on earing. Hardness, ductility and strength variations with earing were also studied. Earing was at an aneeal-temperature. The relationship of earing to hardness, ductibility and strength properties were observed to follow the same pattern. Hardness, ductility and strength properties of cold-rolled and temper-annealed Aluminium 1200 at lowest eaaring did not necessarily correspond to the materials lowest hardness, highest ductility or lowest strength respectively and were found to vary for varying degrees of cold-roll.
Effect of degree of deformation on the mechanical properties of high temperature thermomechanically treated steel
(Asian Network for Scientific Information, 2006) Omotoyinbo, J. A; Olorunniwo, O. E; Ogundare, O.; Oluwole, O. O
The development of hgh strength materials, coupled with good formability, has always been the aim of material scientists. The effect of degree of deformation on the mechanical propehes of hgh temperature themomechanically treated steel (HTMT) has been investigated in this study. It has shown that an increase in percent deformation results in improvement in mechanical propehes. In order to have maximum strengthening, heavy deformation and low finishing temperature should be chosen.
Strengthening of Alloy steel by high temperature thermomechanical treatment
(INSInet Publication., 2006) Omotyinbo, J. A.; Olorunniwo, O. E.; Ogundare, O.; Oluwole, O. O.
Micro-alloyed steels produced by controlled rolling are of the most attractive propositions in many engineering applications because of their relative low cost, moderate strength and very good toughness when compared with as-castalloy steel.. This research work has shownthe possible substitution of cheaper, low-alloy steel for the high alloy steel for the same application. The effect ofHTMT onthe mechanical properties of low alloy steel was investigated.
