Introduction Ni3Al-base alloy (IC) is one of the important high temperature engineering materials [1].
The fusion organization of weld seam in the fine grain materials is smaller than it in coarse grain.
Figure 2 shows the sensitivity of cracking for the coarse grain and fine grain materials.

Introduction Lignin, like cellulose and hemicelluloses, is a major component of plant materials and the most abundant form of aromatic carbon in the biosphere.
Sodium lignosulfonate (NaLS), a by-product of papermaking industry, is a half natural polymer material [2,3], which meets the requirement of polymer additive for water-based drilling fluids.
The interesting of our research group is to develop oil field chemicals or additives from biobased materials, such as lignin, cellulose, maizena and tree gum.

Due to their potential improvement of ionic and/or electronic conductivity, suitably doping, Bi2Al4O9-based ceramics can be utilised in fuel cells as electrolyte and/or cathode materials.
Such as the Sr2+ and Ca2+ doped Bi2Al4O9 has been considered as promising candidate for alternative electrolyte materials [3, 6].
