Oxidation of an as-gas atomized Al powder prevents the transformation of interparticle boundaries (IPBs) into γ-Al₂O₃ nanoparticle-decorated grain boundaries in the bulk Al prepared by spark plasma sintering, and leads to formation of continuous γ-Al₂O₃ layers with nanopores at the IPBs, causing a dramatic decrease of the elongation to fracture.

粉末氧化对铝粉火花等离子烧结法制备块状铝颗粒间边界和力学性能的影响

一个作为气体的氧化雾化铝粉末防止颗粒间的边界（IPBS）插入的转化的γ-Al ₂ ö ₃纳米颗粒的装饰在本体的Al制备通过火花等离子体烧结晶粒边界，并导致形成连续的γ-Al系₂ IPB处具有纳米孔的O ₃层，导致断裂伸长率显着降低。
