摘要：

3 alloys of copper-bearing steels with or without boron have been studied in different thermomechanical controlled processing (TMCP) conditions. The influence of TMCP schedules onto the ageing behaviour in boron-treated and boron-free steels is examined. The structure property analysis of these steels is also carried out. It is found that when the finish rolling is carried out above Ar,, the steels direct cooled after TMCP are able to retain a higher amount of copper in solid, leading to higher ageing response. Boron is found to delay the precipitation of copper and the best ageing effect is recorded in B-Cr steel.
