The results show that the microstructure of the cladding wire by drawing at room temperature is vimineous grain as fibril shape from prime equiaxed grain. The fibril diameter is in inverse proportion to deformation and the fibril length is in direct proportion to the square of deformation approximately. The ultimate tensile strength of the cladding wire by drawing at room temperature goes up in direct proportion to square root of deformation, whereas the elongation decreases and fluctuates.

The L2 glass with 30 mass% Al2O3 filler (L30A) can be fully densified at 800oC in 1 h and devitrified at 850oC for 10 min. The sintering scheme has been optimized to achieve limit dissolution of Al2O3 grain and crystallization of equi-axial LaBO3 and flaky LaAl2B3O9 crystals. The final matrix has limited glassy phase.

Molar-tooth structures refer to the aggregations of equal-axised or polygonal microspar calcite with a crystal size of 0.01mm and a clear boundary, which are mainly developed in the Precambrian fine-grained carbonate rocks. The morphology of Molar-tooth can be divided into ribboned, nodular and clastic forms.

臼齿构造是特指那些发育在前寒武纪细粒碳酸盐岩中有清晰边界、粒度在0.01mm左右的由等轴或多边形的微亮晶方解石组成的集合体，其形态可分为条带状构造、瘤状构造及棱角碎块状构造。

It was believed that either alumina reacted with impurities in the iron powder or the surface diffusion caved the alumina particles to stick to the iron powder surfaces. Another approach was to use the air classifier mill to break up the sintered iron cakes into powders. The morphology of such particles was classified into 4 types in this study: irregular, equalaxed, near spherical, and flaky. The morphological differences were affected by the extent of sintering. The higher the extent of sintering, the stronger the inter-particle bonding.

此外，本实验利用空气分级气流粉碎机将还原后的烧结体进行粉碎，实验结果显示粉碎后的粉末形貌可以分为四种，不规则形、等轴形、近球形和片形，形貌上的差异是由於还原时铁粉烧结程度的不同，烧结程度越高，粉末间键结强度越强，因此粉碎过程中会产生高程度的塑性变形，以至於粉末形貌越来越接近球形，最后因粉末表面大量加工硬化产生破裂，形成片状碎屑。

The suitability of the different processes was analyzed by observing the weld appearance,studying the microstructure and measuring the mechanical properties of the joint.The results show that a favorable weld can be obtained under the suitable parameters by laser beam welding or tungsten inert gas welding with filler metal.The TIG welded joint has a wider HAZ,and the laser welde...

试验结果表明：在工艺参数合适的条件下，加焊丝TIG焊和激光焊均能获得成形较好的焊接接头；TIG焊接头热影响区较宽，焊缝深宽比小，而激光焊时热影响区不明显，焊缝深宽比大；两种焊接方法所获得的焊缝区组织均为均匀的等轴晶，但激光焊时焊缝组织更细，从而使接头抗拉强度大幅度提高，达到母材的94%左右。

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。

The substructure in the deformed specimens consists of very small amount and fine precipitates with equaixed polygonized subgrains in the elongated grains and developed serrations in the grain boundaries.
