Description
結晶の大きさや成長速度は、温度、及び、その温度が材料に作用している時間の長さに依存するという事実によれば、これらの方法では、制御された材料特性を有する物体を得ることはできない。
WO2008/039134で開示されたタイプの自由造形技術(freeforming technique)が、本発明の方法において使用されうるが、製造される物体中における複合体の含有量を所望の量とするために、工程が制御されるという点においては異なる。金属粉末層が熱伝導ベースに適用され、かかる層の限定されたエリアが放射銃を用いて逐次的に融解され、また、かかるエリアがアモルファス金属の状態に凝固されうるように冷却される。本発明において、放射銃は、前記層の一又は複数部分の融解との関連において、アモルファス金属のマトリクス中に結晶性又はナノ結晶性金属粒子の複合体が形成されるように規定された時間−温度曲線に従って、融解エリアが冷却されるように調整される。かかる方法は、所望の範囲の前記複合体を含有する連続層が形成されるまで繰り返される。新たな粉末層が適用されてかかる方法が繰り返され、三次元物体を逐次的に構築するために、前記の新たな層が下層に融合される。
