一般的な金属材料の基本変形とジルコニアセラミックスの弾性率は何ですか?

2026-07-30

けれども
ジルコニアセラミック
高い融点と沸点、高い硬度、および分離に対する耐性を特徴とする材料であり、それは耐えることができます。 

外力の影響下での変形;しかし、この変形は可逆的であり、材料が元の形状に戻ることを意味します。 

外力が取り除かれたら。

一般的に静的引張下で破壊する前に弾性変形と塑性変形の両方の段階を経る金属材料とは対照的に 

室温の負荷-ジルコニアの製陶術は別様に振る舞います。それらは一般に塑性変形の段階を示しません;代りに、もろい 

弾性変形の直後に、最小限の歪みで破壊が発生します。面積の伸びと減少は事実上ゼロです。

金属材料の場合には、もろい鋳鉄はよい引張強さを表わします;但し、ジルコニアの製陶術は別のふるまいをしま、表示します 

圧縮弾性率が引張弾性率よりも著しく高く、圧縮下でわずかな塑性変形がある。

テストはジルコニアの製陶術の弾性率が金属のそれよりずっと大きいことを示します。この係数は性質にだけでなく、左右されます 

原子結合だけでなく、構成相の種類、比率、分布、および空隙率についても、形成および焼結以来 

プロセスは弾性率に大きく影響します。

ジルコニアセラミックスは脆い材料として、引張強度をはるかに上回る圧縮強度を持っています。金属材料と比較して、 

彼らは優れた高温クリープ耐性と可塑性を示し、高温環境での応用に適しています。
