摘要： PROBLEM TO BE SOLVED: To obtain a titanium-carbonitride base alloy for a cutting tool made of cermet having long service life by regulating respective areas of black core parts in hard-phase grains to specific values and regulating the proportion between the grain having larger area of black core part and the grain having smaller area of black core part to values in a specific range. SOLUTION: The cross section of a titanium-carbonitride-base alloy is observed under a scanning electron microscope. Black core parts 1, being enriched in Ti and showing black, are located in respective core parts of hard-phase grains A, B of the alloy, respectively, and a gray peripheral structure 2 is located in the peripheral part of each black core part 1. When a grain, in which the area of the black core part 1 comprises >=30% of the area of the grain as a whole, is called grain A, and a grain, in which the area of the black core part 1 comprises

摘要： PROBLEM TO BE SOLVED: To obtain a titanium-carbonitride-base alloy for a cutting tool made of cermet having long service life by observing a titanium-carbonitride-base alloy under a scanning electron microscope and regulating respective areas of black core parts in hard-phase grains so that they distribute in a manner to form specific two peaks. SOLUTION: The cross section of a titanium-carbonitride-base alloy is observed under a scanning electron microscope. Black core parts, being enriched in Ti and showing black, are located in respective core parts of hard-phase grains in the alloy, and a gray peripheral structure is located in the peripheral part of each black core part. The distribution of the areas of the black core parts is regulated so that it has two peaks: a first peak lies where the areas of the black core parts ranges from 0.1 to 0.7 μm ; a second peak lies where the areas of the black core parts ranges from 0.8 to 2.5 μm . The grains at the first peak are increased in respective areas of the peripheral structures and contribute to breakage resistance. The grains at the second peak are increased in the areas of the black core parts and accordingly contribute to wear resistance. It is preferable to regulate the hard phase to 80-95 wt.%.

摘要： PROBLEM TO BE SOLVED: To provide a titanium carbonitride base alloy, improved in breakage resistance as a defect of titanium carbonitride-base alloy and excellent in wear resistance. SOLUTION: This titanium carbonitride-base alloy has a composition consisting of, by weight, 80 to 95% of hard phase composed of the carbide, nitride, or carbonitride of Ti and at least one metal selected from the group IVa, Va, and VIa metals of the periodic table, other than Ti, and the balance binding phase composed essentially of Co and Ni with inevitable impurities. In this case, when observation is made by the scanning electron micrographs, a grain of the hard phase in the alloy consists of a black core part which looks black in its core and a peripheral structure which looks gray in its peripheral part (a structure with core). Further, when a grain, in which the area of the black core part comprises >=30% of the area of the entire grain, is represented by grain A and also a grain, in which the area of the black core part comprises

摘要： PURPOSE: To shorten molding time and sintering time and to enhance the thermal efficiency and the quality of products by at the time of sintering connecting and interlocking a press molding machine and a heating and annealing furnace and sintering compacts to be sintered right after molding at the time of producing a hard alloy by powder metallurgy. CONSTITUTION: The raw material powder compounded to a prescribed compsn. is added and mixed with a lubricant and an org. binder and is ground and the powder mixture formed in such a manner is packed into the metal molds and is press molded by the press molding machine 1 at the time of producing the hard allay consisting of a sintered hard alloy, cermet or ceramics. Next, the compacts 3 to be sintered after the molding are immediately sent by a feeding mechanism 2 and by utilizing light energy to the sintering furnace 4 which is divided to an org. lubricant removing section 5 and a sintering section 6. The compacts 3 to be sintered are subjected to removal of the lubricant and the org. binder at a prescribed temp. by a heater 9 in the removing section 5 and are sent to the sintering section 6, where the compacts are sintered by a light source section 10 having good thermal efficiency. As a result, the productivity is improved and since the sintering conditions are variable by every work, the quality is improved.
