When the Al-Mg-Zr-Sc welding wire was used as filling material,the grains of welding seam were refined obviously,and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone .

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

The strength of HSLA steel with ferritic plus pearlitic mierostruetures has attained the limited value of 450～500MPa by traditionally microalloying treatment and TMCP. In order to further improve the strength grade, low carbon bainitic steel plates should be developed.
