Abstract: front page image
(EN) Provided is a friction stir welding tool member made of a silicon nitride sintered compact, characterized in that the silicon nitride sintered compact contains additive components other than silicon nitride in an amount not exceeding 15 mass%, and that the additive components include at least one element selected from lanthanoids and at least one element selected from Mg, Ti, Hf, and Mo. It is also preferable to contain at least one element selected from Al, Si, and C as an additive component. According to this configuration, the present invention is able to provide a highly durable friction stir welding tool member.
(FR) L'invention concerne un élément d'outil de soudage par friction-malaxage composé d'une pastille frittée en nitrure de silicium, caractérisé en ce que la pastille frittée en nitrure de silicium contient des composants additifs autres que du nitrure de silicium en une quantité ne dépassant pas 15 % en masse, et en ce que les composants additifs comprennent au moins un élément sélectionné parmi les lanthanides et au moins un élément sélectionné parmi Mg, Ti, Hf et Mo. Il est également préférable de contenir au moins un élément sélectionné parmi Al, Si et C en tant que composant additif. Selon cette configuration, la présente invention peut fournir un élément d'outil de soudage par friction-malaxage hautement durable.
(JA) 窒化珪素焼結体から成る摩擦攪拌接合用ツール部材であって、上記窒化珪素焼結体は窒化珪素以外の添加成分を15質量%以下含有すると共に、上記添加成分としてランタノイド元素から選択される少なくとも1種と、Mg、Ti、Hf、Moから選択される少なくとも1種とを含有することを特徴とする。また、添加成分として、Al、Si、Cから選択される少なくとも1種を含有することが好ましい。上記構成によれば、耐久性が高い摩擦攪拌接合用接合ツール部材を提供できる。
