摘要： The present invention relates to a process of producing a permanent magnet, which includes extruding a preform to form a plate-shaped permanent magnet, in which the preform is extruded in such a way that a dimension of a cross section of the preform is reduced in an X-direction and enlarged in a Y-direction perpendicular to the X-direction. The present invention also relates to a plate-shaped permanent magnet formed by extruding a preform, in which the preform is extruded in such a way that a dimension of a cross section of the preform is reduced in an X-direction and enlarged in a Y-direction perpendicular to the X-direction, whereby the permanent magnet has a strain ratio ε2/ε1 with respect to the preform in a range of 0.2 to 3.5, in which ε1 is a strain in the direction of the extrusion of the preform and ε2 is a strain in the Y-direction.

摘要： An improved method of forging a precipitation hardening type stainless steel. The method comprises the steps of soaking the precipitation hardening type stainless steel at a temperature of austenitizing range, cooling the steel to a temperature in the range of 200-700° C., preferably 400-600° C., and subjecting the steel to forging at the temperature in this range. Conventional lubricants and die cooling oils can be used without being deteriorated due to high temperature. It is preferable to forcibly cool the soaked steel to adjust the temperature of the steel at which it is forged. The forged steel is then age hardened to exhibit inherent hardness.

摘要： A high-strength member of precipitation hardening martensitic steel is manufactured through the steps of heating precipitation hardening martensitic stainless steel at an austenitizing temperature, performing the first plastic working at a temperature between 200.degree. C. and 700.degree. C. so as to leave a part of austenite as retained austenite at the time of cooling the steel at Ms point or below thereafter, cooling the steel at the temperature not higher than Ms point, performing the next plastic working at a temperature not higher than As point so as to transform the retained austenite into martensite, and performing age hardening treatment at a temperature between not lower than 370.degree. C. and lower than 480.degree. C.

摘要： A titanium alloy is prepared containing 2 to 4% by weight of aluminum, 1.5 to 2.5% by weight of vanadium, 0.20 to 0.45% by weight of a rare earth element (not essential). 0.05 to 0.11% by weight of sulfur (not essential), and titanium substantially for the remainder, the ratio of the rear earth element content to the sulfur content ranging from 3.8 to 4.2. This titanium alloy is rough-formed and hot-forged at a temperature in a .beta. region, and the resulting titanium alloy ingot is processed directly into a titanium alloy component having a desired shape. The titanium alloy component thus manufactured has a satisfactory fatigue strength and is also excellent in machinability, and can be used for connecting rods, valves, retainers, etc. to be incorporated in the engine of an automobile.
