다국어 초록 (Multilingual Abstract)
Effects of the aging treatment on the mechanical properties of 0.5-2.0% Cu-added hot rolled steel sheets were investigated by Vickers hardness measurement, tensile test and scanning and transmission electron microscopy. The hardness of the specimen coiled at 450℃ was greater than that of 650℃. As increasing Cu contents, the hardness increased and the time to reach peak hardness decreased. It was also found that the aging at 550℃ led to the maximum hardness for all composition. The maximum tensile strength of 1.0, 1.5 and 2.0% Cu-bearing steels aged at 550℃ was 553. 679 and 766㎫ respectively.
It was confirmed by TEM observation that Cu-clusters were finely dispersed throughout the grain inside. The size of Cu-clusters was about 10-20㎚ at peak-aged condition.
