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。

For supercooling directional solidification, ideal directional microstructure can be obtained only within the supercooling range 63~83K and 127~170K. These two supercooling ranges just corresponds to the supercooling for developed equiaxial dendrites in ordinary supercooling solidification.
6对于深过冷定向凝固来说,只有在63~83K的低过冷度范围和127~170K的中过冷度范围才能获得理想的定向生长组织,而这两个过冷度范围正好对应于深过冷熔体凝固组织为发达的等轴枝晶的过冷度范围,这种组织的相似性似乎与过冷度一样具有遗传性。

The welding nugget happened to dynamically recrystallize and the refined crystal grains were obtained and the majority of Mg_2Si particles dissoluted due to the intensive mechanical stir and higher high temperature. In the thermal-mechanical affect zone that was heated under the recrystallized temperature, the crystal grains were elongated due to the mechanical stir and Mg_2Si particles partly dissoluted and the others grew. In the heat affect heat without the mechanical stir, to some extent, both of the crystal grains and the majority of Mg_2Si particles grew.
焊核区受到强烈机械搅拌作用和加热到较高的温度发生动态再结晶,得到细小等轴晶组织,Mg_2Si相以溶解为主;热机影响区加热温度低于再结晶温度,在机械搅拌作用下晶粒由于塑性变形而伸长,Mg_2Si相部分溶解,部分长大;热影响区仅受加热影响,晶粒有一定程度长大,Mg_2Si相以长大为主。

Equiaxed and bigger grains are produced after C.P.Ti is deformed under the high temperature. Besides, many tiny subgrains were found in some of the metallurgical structure. The dislocation reaction caused by the deformation under the high strain rate generates ductile cellular metastructures, while the equiaxed cellular metastructures are generated under the low strain rate. The metallurgical structure of TC4 alloy including lath-shaped hexagonal martensite and trimetric martensite only exists in the higher temperature. The homogeneous, tiny and reticular grain shown after extreme high temperature deformation.
