Description
生数を減少させ、最終的に焼結されたセラミックスの緻密性を向上させる。
a・m1/2のハイエントロピー希土類高靭性タンタル酸塩セラミックスを得た。上述の方法を用いて調製されたハイエントロピー希土類タンタル酸塩セラミックスの高硬度及び高靭性を十分に説明するために、ここではその中の6組の実施例を用いて説明を行う。
ある。
X線回折装置を用いて実施例1~6及び比較例1~3で得られたセラミックス材料について検査を行った。実施例1で得られた(Y1/4Gd1/4Dy1/4Er1/4)TaO4ハイエントロピーセラミックスを例として、XRDパターンを図1に示す。図1では、(Y1/4Gd1/4Dy1/4Er1/4)TaO4セラミックス試料のXRD測定結果における回折ピークは基準PDFカードJCPDS:No.24-1415の基準ピークと一つ一つ対応しており、第二相の回折ピークは存在していない。これは、調製して得られたセラミックス材料の結晶構造は単相であり、不純物相が生じていないことを示している。
ビッカース硬度計を用いて実施例1~6及び比較例1~3で作製したセラミックスの硬度を測定した。その後、圧痕の対角線長さ及び四隅のクラック長さに基づいて材料の破壊靭性を計算した。検査結果を下の表2に示す。実施例6で得られた(Y1/9Gd1/9Dy1/9Er1/9Lu1/9Tm1/9Ho1/9Tb1/9Pm1/9)TaO4ハイエントロピーセラミックスを例として、靭性に係る図を図2に示す。
関係する公式は、次の通りである。ビッカース硬度:
(単位GPa)、HVはハイエントロピーセラミックスのビッカース硬度を示し、Fとdは試験で加える荷重と圧痕の対角線長さをそれぞれ指す。破壊靭性:KIC=0.0725*(P/a3/2)(単位MPa・m1/2)、Pは試験で加える荷重を表し、aは平均クラック長さを表す。
(1)加える希土類酸化物の種類が多いほど、得られる希土類高靭性セラミックス材料の硬度及び靭性がいずれも高くなる。本実施例において、加える希土類酸化物の種類が9種(x=9)であるとき、セラミックス材料の硬度は6.56GPaに達し、靭性は3.54MPa・m1/2に達している。
