摘要

新規材料の探索や物性の最適化を高効率に行う手法として,組rn成や製作条件を系統的に変化させた大量のサンプル群を一括してrn製作し,評価する,コンビナトリアル技術が注目されている.%New compositions of a Pt-Zr-Ni amorphous alloy as a mold material for glass lens production were searched using a new combinatorial synthesis called the combinatorial arc plasma deposition (CAPD). First, 3,267 thin film samples of 1 mm × 1 mm size were deposited by CAPD. The phase and composition of 883 samples of the thickness more than 500 nm were evaluated and 312 amorphous samples were found. Secondly, six amorphous samples expected to have a high crystallization temperature (Tx) and a high tensile strength (σ_B) were deposited using a sputtering system because CAPD samples were too small and thin to evaluate mechanical property such as σ_B.Young's modulus, elastic limits and anti-sticking with melted glass. Finally, Pt_(50)Zr_(36)Ni_(14) was found as a new mold material of a high Tx (985 K), a high σ_B (2.12 GPa) and anti-sticking. The new mold material was also expected to have a high resistance to oxidation at a high temperature range of glass molding.
