Under such a solidification condition that the growth rate is low and the temperature gradient ahead of the solidi fication front is steep, a large amount of α-Al nuclei can be produced by peritectic reaction, during which only metastable Al〓Zr particles or very fine equilibrium Al〓Zr particles rather than larger equilibrium Al〓Zr partiles are involved.

在低的生长速度和高的界面前沿温度梯度条件下,结晶前沿Al〓Zr粒子与液态铝发生包晶反应(只涉及亚稳Al〓Zr或尺寸极小的平衡Al〓Zr,而不涉及尺寸较大的平衡Al〓Zr)产生大量α晶胚,α晶胚呈球面生长,最终形成等轴非枝晶形态。

The results show that, the coefficients of welded joints are both greater than 0.9, but the yield strength of weld joint filled with Al-Mg-Zr-Sc welding wire is greater 100 MPa than that of filled with Al-Mg-Zr welding wire. It indicates that the Al-Mg-Zr-Sc welding wire is the best alteration of filling materials to weld of Al-Mg-Sc alloy.

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。
