The Effects of Gradual Cooling towards Mechanical Behaviour of 7075 T6 Aluminium Rods and Polyvynil Chloride Belts
Author(s): Vikneshwaran Viknesh* and Azizul Rahman
This paper reports the effects of hardening heat treatment and gradual cooling on the mechanical properties of 7075
temper grade 6 aluminium alloys and polyvinyl chloride conveyor belt. The aluminium alloys casted in the form of
round cylindrical rods. Upon casting, the rods machined into dog-bone style prior to the heat treatment and tensile
test. The samples attempted hardening treatment at desired temperatures. A time vs. temperature plotted prior to the
hardening treatment effect. The samples subjected to gradually cooling, by releasing the heat on the surface of some
polyvinyl chloride conveyor belts. Upon accomplishment, entire as-cast samples in each category and heat-treated
samples subjected to tensile test. From the results obtained, there is improvement of mechanical properties because of
gradual cooling... View More»
