Abstract: front page image
(EN) Provided are a sintered body having good wear resistance even under a high speed cutting condition, a cutting tool using the sintered body, and a method for producing the sintered body. The sintered body comprising a first particle group including particles each having a cubic rock-salt structure represented by formula (1) Al(1 - x)CrxN ··· (1) (in formula (1), x is 0.2 ≤ x ≤ 0.8), and a second particle group including particles of at least one kind of first compound selected from the group consisting of oxides or oxynitrides of aluminum, zirconium, yttrium, magnesium and hafnium.
(FR) La présente invention concerne un corps fritté ayant une bonne résistance à l'usure, même sous une condition de coupe à haute vitesse, un outil de coupe utilisant le corps fritté, et un procédé de production du corps fritté. Le corps fritté comprend un premier groupe de particules comprenant des particules ayant chacune une structure de sel gemme cubique représentée par la formule (1) : Al(1 - x)CrxN...(1) (où x est tel que 0,2 ≤ x ≤ 0,8), et un deuxième groupe de particules comprenant des particules d'au moins un type de premier composé choisi dans le groupe constitué d'oxydes ou d'oxynitrures d'aluminium, de zirconium, d'yttrium, de magnésium et d'hafnium.
(JA)  高速切削条件下においても、優れた耐摩耗性を有する焼結体、焼結体を用いた工具および焼結体の製造方法を提供する。下記式(1)で表される立方晶岩塩型構造を有する粒子を含む第1粒子群と、 Al(1-x)CrN・・・(1) (式(1)中、xは0.2≦x≦0.8である) アルミニウム、ジルコニウム、イットリウム、マグネシウムまたはハフニウムの酸化物または酸窒化物からなる群より選択される少なくとも1種の第1化合物の粒子を含む第2粒子群とを有する、焼結体である。
