Hard alloy, and coated tool and cutting tool using same
A cemented carbide of an undefined manner of the present disclosure has; a hard phase containing W and C; a solid solution phase containing W, C, and Ti; and a binder phase containing an iron group metal. The hard alloy has a debeta layer formed only from WC and an iron group metal on the surface of the region where the rake face and the flank face intersect with each other. The average thickness of the beta-removed layer of the rake face in the intersecting region is a, and the average thickness of the beta-removed layer of the flank face in the intersecting region is b. The relationship between a and b satisfies blt; a. A coated tool of an undefined manner of the present disclosure has the cemented carbide and a coating located on the surface of the cemented carbide. A cutting tool according to an undefined embodiment of the present disclosure is provided with: a shank extending from a first end toward a second end and having a sipe on the first end side; and the coated cutter is positioned in the cutter groove.
本公开的未被限定的一方式的硬质合金具有；硬质相，其含有W和C；固溶体相，其含有W、C和Ti；以及粘结相，其含有铁族金属。在硬质合金中的前刀面与后刀面的交叉区域的表面具有仅由WC及铁族金属构成的脱β层。将交叉区域中的前刀面的脱β层的平均厚度设为a，将交叉区域中的后刀面的脱β层的平均厚度设为b。a与b的关系满足b
