    Abstract: According to the present invention, a machining-improving powder is a crystalline layered alkali silicate heat-treated at a temperature range of 400-1100°C, and the mixture constituting the machining-improving powder is set such that an iron-based powder takes up 0.01-1.0 mass% in relation to the total amount of alloy powder and machining-improving powder. As a result, not only can sintering of a compact be performed in a sintering furnace without having any negative effects on the environment inside the furnace, but it is also possible to attain a mixed powder for powder metallurgy by which it is possible to obtain a sintered body having both exceptional lathing properties and exceptional drilling properties.

    Abstract: A flaky powder having an average major-axis diameter of 100 µm or smaller, a thickness of 10 µm or thinner, and an aspect ratio (ratio of major-axis length to thickness) of 5 or higher is incorporated into an iron-based powder in an amount of 0.01-5.0 mass% to thereby obtain an iron-based mixed powder. This iron-based mixed powder has enhanced flowability, gives compacts having an improved density, and enables the formed compacts to be ejected at significantly reduced force. Consequently, an improvement in product quality and a reduction in production cost are attained.

    Abstract: In an iron-based powder, 0.01% to 5.0% by mass of a flaky powder having an average particle size of longitudinal size of 100 µm or less, a thickness of 10 µm or less, and an aspect ratio (longitudinal size-to-thickness ratio) of 5 or more with respect to the iron-based mixed powder is contained, whereby the flowability of an iron-based mixed powder is increased, the density of a green compact is increased, and ejection force is greatly reduced after compaction, thereby accomplishing an increase in product quality and a reduction in production cost.
