OS0909 傾斜機能特性を有するTiNi形状記憶合金の変態特性評価
詳細
Functionally graded TiNi shape memory alloy wires were fabricated using powder metallurgy and plastic working processes. In the sintering process, mixed TiNi powders of several compositions were prepared using ball milling process. The prepared powders were filled layer by layer into the graphite die. The sintered TiNi SMA billets were extruded to wires at 1073 K. Transformation temperatures and stress-srtain curves in the several parts of the extruded wires were investigated.
