摘      要：The HIPERC study was a European research project involving several steel companies and research organisations which examined the effects of alloying elements and processing conditions in low carbon (0.09 wt %),niobium containing (0.05%-0.12 wt.%) ***-scale heats and pilot rolling trials simulating air and water-cooled plate production as well as hot-rolled strip production were made and the effects of C,Mn,Ni,Cu,Cr,Mo,Nb,Ti and B on transformation characteristics and temperatures of recrystallisation *** equations for the characterisation of microstructure,tensile and impact properties and for the weldability of these steels were *** were manufactured and processed into plate and coil-plate by three steel companies and pipe produced from both *** from these,plus thicker plate for structural use,were determined and these compared well with the values predicted from the regression *** project has shown that excellent combinations of strength,toughness and weldability can be obtained for a wide variety of *** benefits were seen and recommendations on altering the limits for niobium in Euronorms have been proposed.
