Description
上記の英国特許出願公開第２，２３４，５２１ Ａ号明細書からは、ニッケルベース超合金に硼素または炭素が富化することによって指向性凝固の場合に等軸化した又はプリズム状の構造を有する微細構造を有する組織が生じることも公知である。炭素及び硼素が高温で安定している粒界の所に炭化物及び硼化物を析出させるので、炭素及び硼素が粒界を強化する。更にこれらの元素が粒界中に及び粒界に沿って存在することが、粒界の弱さを引き起こす拡散進行を減退させる。それ故に、１０°〜１２°に無秩序状態を増加させそしてそれにも関わらず高温で材料の良好な性質を達成することが可能である。しかしながら、特にニッケルベース超合金の鋳造した単結晶部品の場合にこの小角粒界が性質にマイナスの影響を及ぼす。 From the above-mentioned British Patent Application No. 2,234,521 A, the nickel-base superalloy has an equiaxed or prismatic structure in the case of directional solidification by enrichment of boron or carbon. It is also known that a microstructure having a microstructure is formed. Carbon and boron precipitate the carbides and borides at the grain boundaries where the carbon and boron are stable at high temperatures, so the carbon and boron strengthen the grain boundaries. Furthermore, the presence of these elements in and along the grain boundaries reduces the diffusion process that causes the grain boundaries to weaken. It is therefore possible to increase the disordered state from 10 ° to 12 ° and nevertheless achieve good properties of the material at high temperatures. However, this small-angle grain boundary has a negative effect on properties, particularly in the case of single crystal parts cast from nickel-base superalloys.
炭素及び硼素は、これらの元素が粒界の所に高温において安定している炭化物及び硼化物を析出するので、粒界を、特にニッケルベース超合金よりなるＳＸ−またはＤＳ−ガスタービンの場合に＜００１＞−方向で生じる小角粒界も強化する。更にこれらの元素が粒界中に及び粒界にそって存在することが粒界の弱体化の主原因である拡散進行を減少させる。これによって長い単結晶部品、例えば約２００〜２３０ｍｍの長さのガスタービンのタービン翼及び羽根の鋳造性を著しく改善する。 Carbon and boron precipitate carbides and borides that are stable at high temperatures at the grain boundaries, so that the grain boundaries can be made particularly in the case of SX- or DS-gas turbines made of nickel-based superalloys. The small-angle grain boundaries that occur in the <001> -direction are also strengthened. Furthermore, the presence of these elements in and along the grain boundaries reduces the diffusion progression which is the main cause of grain boundary weakening. This long single crystal components, significantly improves the turbine blades and vanes of the casting of eg about 200 to 230 mm of the length of the gas turbine.
合金Ｌ１について記載した含有量５０ｐｐｍのＹ及び１０ｐｐｍのＬａが特に有利である。何故ならばＬ１が塗布すべきＴＢＣ−層と特に良好な適合性を有するからである。更にこれらの２種類の元素は環境の影響に対する耐久性も増加させる。これらの元素をこの僅かな範囲内の量で添加することによって、合金表面のアルミニウム−／クロム酸化物−スケール層を安定化させそして顕著に優れた耐酸化性を実現する。Ｙ及び／又はＬａは、ベース材料へのスケール層の接合性を改善する。繰り返し酸化する耐久性はＴＢＣ−層の安定性の主要な要因である。 The content of 50 ppm Y and 10 ppm La described for alloy L1 is particularly advantageous. This is because L1 has a particularly good compatibility with the TBC layer to be applied . Furthermore, these two types of elements also increase the durability against environmental influences. The addition of these elements in amounts within this small range stabilizes the aluminum / chromium oxide-scale layer on the alloy surface and achieves significantly better oxidation resistance. Y and / or La improves the adhesion of the scale layer to the base material. The durability of repeated oxidation is a major factor in the stability of the TBC layer.
