| Popis: | Cryorolling is indeed a very suitable approach in producing a good Al alloy of Al 5083 with exceptionally strong and hard properties. This new Severe Plastic Deformation (SPD) methods can bring out the utmost of strength in Al alloy compare with cold rolling. This paper hence discussed the effect of dipping duration of Al alloy in liquid nitrogen prior to rolling process to its improved mechanical properties such as hardness and tensile strength. The result showed that the hardness increased with increasing dipping time until 60 minutes for low temperature pre-anneal and 30 minutes for high temperature pre-anneal and later dropped. The tensile strength of cryorolled sample also showed some improvement for about 5-8% compared with normal cold rolling. |
