Summary: | This heat-resistant sintered material has a composition which contains, in mass% as a whole composition, 20-38% of Cr, 0.5-3.0% of Mo, 3.0-7.0% of Si and 0.5-2.5% of C with the balance made up of Fe and unavoidable impurities. This heat-resistant sintered material has a structure wherein hard phases are dispersed in a matrix; the matrix contains Fe, Cr, Mo and Si; the hard phases contain Cr, Fe, Mo and C; and the porosity is 2.0% or less.
Le matériau fritté résistant à la chaleur selon l'invention a une composition qui contient, en % en masse de la composition totale, de 20 à 38 % de Cr, de 0,5 à 3,0 % de Mo, de 3,0 à 7,0 % de Si et de 0,5 à 2,5 % de C, le reste étant constitué de Fe et d'impuretés inévitables. Ce matériau fritté résistant à la chaleur a une structure dans laquelle des phases dures sont dispersées dans une matrice ; la matrice contient Fe, Cr, Mo et Si ; les phases dures contiennent Cr, Fe, Mo et C ; et la porosité est inférieure ou égale à 2,0 %.
