摘要： PURPOSE: To obtain the ferrous sintered alloy having improved strength, by incorporating specific mother alloy powder giving liquid phase during the stage of sintering and graphite powder to the ferrous powder for powder metallurgy by specific percentage, compacting them, and sintering the compact under specific conditions.
CONSTITUTION: The mother alloy powder (0.5W8wt%) consisting of 2W30wt% W, 2W6wt% C, and the balance Fe with inevitable impurities and giving liquid or liquid + solid phase at 1,080W1,200°C and the graphite powder (≤1.5wt%) are incorporated to the ferrous powder for powder metallurgy. The mixed powder is compacted with the addition of a lubricant such as zinc stearate by a conventional method, and sintered under such conditions as to give a liquid phase of the mother alloy powder. In this way, the density is made higher and the alloying elements are diffused, so that the high-strength ferrous sintered alloy can be obtained obviating the necessity of heat treatment.

摘要： PROBLEM TO BE SOLVED: To provide a heat treatment method of a plated steel sheet for hot pressing, a method in which a hot-press formed article having sufficient coating adhesion and corrosion resistance can be stably obtained. SOLUTION: According to this heat treatment method of a plated steel sheet for hot pressing, the plated steel sheet is heat treated before hot pressing in which rapid cooling for quenching is performed in a press mold. For this purpose, a slab specimen 10 is heated in the atmosphere in which oxygen concentration is >0 volume % or in which oxygen concentration is ≥0 volume % with dew point ≥0°C. Accordingly, on the surface of the slab specimen 10, there is formed a metallic oxide layer of the plating material, namely, a barrier layer such as zinc oxide or zinc hydroxide, for example. Thus, rapid oxidation is suitably suppressed when the article is taken out from a heating furnace, enabling the hot-pressed article to be stably obtained that has sufficient coating adhesion and corrosion resistance.
