熱を利用して形状記憶合金を変形させると、元の形状に戻ります。形状記憶合金は、より強い高温形態 (オーステナイト) からより弱い低温形態 (マルテンサイト) に冷却されるときに、結晶構造の相転移を起こします (マルテンサイト)。これらの合金の固有の相転移により、形状記憶や超弾性などのユニークな特性が生まれます。マルテンサイト状態にある形状記憶合金を新しい形状に曲げるのは非常に簡単です。合金は変態温度で変態し、大きな力で元の形状に戻ります。「形状記憶」という用語は、この変態プロセスを指します。
自動車産業の成長は、形状記憶合金市場を牽引する主な理由の 1 つです。形状記憶合金の需要は、土木、ロボット工学、防衛、生物医学、航空宇宙などの他の産業における大きな発展によってさらに高まっています。ユーザーのニーズに合わせて曲げたり伸ばしたりできる形状記憶合金は、民生用電子機器の普及に伴い人気が高まっています。形状記憶合金市場は、ニチノール合金の人気の高まりによっても牽引されています。ステント、歯科用ワイヤー、整形外科用ネジ、その他の外科用品などの医療用インプラントは、形状記憶金属で作られています。形状記憶合金市場は、いくつかの問題により、一定の成長制限が見込まれています。これらの合金は価格が高く、製造プロセス全体で材料の品質が敏感であるため、市場は制約されています。形状記憶合金の最終用途産業の中で最も成長率が高いものの 1 つは、民生用電子機器と家電製品です。形状記憶合金は、携帯電話、エアコン、コーヒーメーカー、カメラ、パーソナルアクセサリー、炊飯器などの製造によく使用されています。これらの合金は、弾力性が向上し、疲労寿命が長く、耐腐食性があるため好まれています。主に、さまざまな電気機器や家庭用アプリケーションでアクチュエータやセンサーとして使用されています。

技術の進歩、研究開発の取り組みの強化、低侵襲医療機器の需要の高まりが、市場拡大の主な原動力となっています。形状記憶合金 (SMA) は、消費者向け電子機器、航空部品、エンジニアリングおよび製造アクチュエータ、バイオメディカル機器、外科用機器の製造においてますます必要になってきています。世界市場の拡大は、高品質の救命医療機器や、自動車および航空宇宙部品の改良に対する需要の高まりによるものです。
COVID-19の流行は、形状記憶合金(SMA)の世界市場に相反する影響を及ぼしています。一方では、パンデミックにより、経済の減速とサプライチェーンの混乱により、航空宇宙や自動車などのいくつかの最終用途産業からの需要が減少しました。対照的に、ヘルスケア部門では、パンデミックに対応して、医療用ツールとサプライ、特にSMAの需要が増加しました。COVID-19症例の発生率の上昇と医療ソリューションの需要により、ステント、整形外科用インプラント、手術器具などの医療機器に使用されるSMAの需要が大幅に増加しました。ただし、パンデミックが製造とサプライチェーンに与えた影響により、これらの機器の生産と配送に若干の遅れが生じており、市場に即時の影響を及ぼす可能性があります。現在、政府はインフラの構築よりも基本的な人間のニーズを満たすことに重点を置いており、これが土木建設業界からの形状記憶合金の需要増加につながっています。
The Shape Memory Alloys Market is expected to grow at 11.2% CAGR from 2022 to 2029. It is expected to reach above USD 25.74 Billion by 2029 from USD 9.9 Billion in 2020.
