- 論文の詳細を見る
Al-Fe alloys with composition 1.0, 2.5, 5.0at.%Fe are fabricated by repeated compaction and backward extrusion in a closed die set using raw materials as elemental powder mixture. This process is done in solid state at room temperature. The produced alloyed preforms are further consolidated by hot forging to achieve high density billet. Alloyed preforms are tested for thermal stability by using differential thermal analysis. Phase changes during heating are investigated by using x-ray diffraction, and confirmed by scanning electron microscope using EDS line scan mode. The alloyed billets are subjected to tensile test.
