Study on the Effect of Artificial Aging on Tensile Property of Reinforced Bar in Coil
Reinforced bar in coil after straightening,the tensile test did not yield obviously.An extensometer is required to detect Rp0.2 instead of ReL.But different testing conditions and personnel have great influence on Rp0.2 testing results.In this paper,a method for the stable measurement of yield strength is given by artificial aging at different temperatures.The stable test results can be given in the process of production process adjustment.
