Description
ハイブリッド焼結炭化物合金を、本発明の方法により調製した。図4Bを参照のこと。図4Bに示されるハイブリッド焼結炭化物合金45の態様では、連続相46は靭性が高くひび割れに耐性がある層であり、分散相47は硬質の耐磨耗性相である。図4Bの態様の2つの相の組成及び体積比は、上記の図4Aのハイブリッド焼結炭化物合金と同じである。しかしながら、ハイブリッド焼結炭化物合金を製造する方法が異なっており、ハイブリッド焼結炭化物合金の微細構造及び特性において生じた違いが有意である。分散相47の粒はブレンドする前に焼結されたので、分散相47の粒はブレンド物の固化成形時に有意には崩壊せず、その結果、図4Bに示される態様の接触率は0.31となった。有意には、この態様の接触率は、それぞれ0.52及び0.5の接触率を有する図2及び4Aに示されるハイブリッド焼結炭化物合金の接触率よりも低い。接触率における低減は、ハイブリッド焼結炭化物合金全体の特性に有意な効果を与える。図4Bに示されるハイブリッド焼結炭化物合金の態様の硬さは、15.2Mpa.m1/2であり、図4Aに示されるハイブリッド焼結炭化物合金に対して18%を超える増加である。これは、分散相領域間の交差点の数が低い結果であると考えられ、故に、硬質の分散相領域47のいずれかで始まるひび割れの広がりが、靭性の高い連続相46により中断されるだろう。本発明の方法は、ハイブリッド焼結炭化物合金の接触率を、ハイブリッド焼結炭化物合金における分散相の体積分率の1.5倍より少なく制限することを可能とし、一定の適用では、ハイブリッド焼結炭化物合金の接触率を、分散相の体積分率の1.2倍よりも少なく制限することは有利である。
ハイブリッド焼結炭化物合金が、本発明の方法により調製された、硬質焼結炭化物合金であるFK10FTMの粒を、1000℃で焼結させた。焼結されたFK10FTM焼結炭化物合金の粒を、“未加工”又は未焼結の2055TM焼結炭化物合金の粒とブレンドした。次いで、焼結された粒と未焼結の粒とを含んでなるブレンド物を、固化成形し、慣用的な手法を用いて焼結させた。堅いダイにおける機械的又は液圧によるプレス、並びにウェットバッグ又はドライバッグの平衡プレスのような、慣用技術を用いた粉末固化成形が用いられる。最終的には、慣用的な真空炉における液層温度で、又はSinterHip炉における高圧での焼結を行うことができる。図5Bを参照のこと。図5Bに示されたハイブリッド焼結炭化物合金55の態様では、連続相56は靭性の高いひび割れ耐性がある相であり、分散相57は硬質の耐磨耗性相である。図5Bの態様の2つの相の組成及び体積率は、上に記載された、慣用的な方法により調製された図5Aのハイブリッド焼結炭化物合金と同じである。図5A及び5Bの両方のハイブリッド焼結炭化物合金の分散相の体積分率は、0.45である。しかしながら、ハイブリッド焼結炭化物合金を製造する方法が異なっており、ハイブリッド焼結炭化物合金の微細構造及び特性における違いが有意である。分散相57の粒は、ブレンドする前に焼結されたので、分散相57の粒は、ブレンド物の固化成形時に崩壊せず、結果として、図5Bに示されたハイブリッド焼結炭化物合金の態様の、0.48の接触率をもたらす。有意には、この態様の接触率は、0.75の接触率を有する図5Aに示されたハイブリッド焼結炭化物合金の接触率よりも低い。接触率における低減は、ハイブリッド焼結炭化物合金全体の特性に有意な効果を与える。図5Bに示されたハイブリッド焼結炭化物合金の態様のパームクイスト靭性は、13.2Mpa.m1/2であり、図5Aに示されたハイブリッド焼結炭化物合金の10.6Mpa.m1/2のパームクイスト靭性に対して25%の増加である。これも、分散相間の交差点の低減の結果であると考えられ、故に、硬質の分散相57において始まるひび割れの伝達は、靭性の高い連続相56により中断されるだろう。
図7は、サンプルNo.1〜11から得られたデータのプロットである。容易にわかるように、本発明の方法によりハイブリッド焼結炭化物合金は、特性、靭性、及び耐磨耗性の改良された組み合わせを有する。本開示の複合材料は、数多くの適用に特に適した物品、例えば、削岩(採鉱及び原油/ガス探査)適用、建築に用いられる機械の摩擦用部品として、鋼鉄や他の金属の熱間圧延におけるロール材料として、そして、衝撃形成適用、例えば冷間形成等における物品へと組み立てられることができる。
