| 摘 要： | Ｃｕ能显著提高低碳ＨＳＬＡ钢的强度；时效状态下，添加１％以上的铜可使钢的屈服强度提高１５０￣２００ＭＰａ，抗拉强度提高１６０￣１７０ＭＰａ，但钢的韧性有所降低。当提高时效温度时，不同Ｃｕ含量钢的强韧性差异减小。

| Abstract: | The
test results show that the strength of low carbon HSLA steel increased obviously by adding Cu,
and as the Cu content added was more than 1 %, for the aged steel the yield strength increased by
150200 MPa, and the tensile strength increased by 160170 MPa with the toughness of steel
decreasing slightly. As the aging temperature increased the difference of strength and toughness
of the steels with various Cu content reduced. |
