摘要： PROBLEM TO BE SOLVED: To provide a method for producing a Ti-Al based alloy target material which can not only provide a Ti-Al based alloy target material having extremely high bending strength, and therefore free from damage to the collar part of the target due to thermal stress upon film deposition, but also can uniformly deform a raw material composition upon press molding, consequently dispenses with dimensional correction by post-working and can remarkably increase the yield of the raw material composition.
SOLUTION: In the method where a raw material composition comprising Ti powder and Al powder is press-molded, and next, the obtained molding is subjected to sintering or sinter forging to produce a Ti-Al based alloy target material, the press molding is practiced by compressing the raw material composition at 80 to 250°C in a die.

摘要： PROBLEM TO BE SOLVED: To provide a lubricant evaluation method capable of evaluating accurately lubricating performance of a lubricant applied on a side face of a metal raw material in plastic working. SOLUTION: The plastic working is carried out to project an intermediate part of a metal test piece A flange-likely toward an outer circumferential side, by pressing clampingly the metal test piece A from both end faces thereof at a fixed stroke, and the lubricating performance of the lubricant is evaluated based on a pressing load Wp to the metal test piece A therein. The lubricating performance of the lubricant applied on the side face of the metal raw material in the plastic working is evaluated accurately, since the lubricating performance of the lubricant applied on the side face of the intermediate part of the metal test piece A has a close influence to the plastic working for projecting the intermediate part flange-likely toward the outer circumferential side.

SOLUTION: In the method for heat-treating a steel material, e.g., a workpiece made of a steel material heated to a suitable temperature between Ac1 and Ac3 and plastically deformed into the shape of an outer ring member by forging is introduced into a heat treatment furnace when the workpiece still retains the heat applied thereto during the plastic deformation as its temperature is reduced. In the heat treatment furnace, the outer ring member is heated preferably at a heating rate of 15 to 50°C/min and held at a temperature between Ac1 and Ac3 for 10 minutes or less, preferably for about 3 min (first stage S1). Then, the outer ring member is slowly cooled at a cooling rate of 5 to 45°C/min, preferably of 5 to 10°C/min (second stage S2).
