摘要： PURPOSE:To satisfy characteristics required for a body portion and the acute angle portion of the peripheral edge of a nozzle hole portion at the same time by forming a re-melted treatment layer which is treated using high-density energy on the acute angle portion at least of the peripheral edge portion of the nozzle hole portion. CONSTITUTION:On the acute angle portion 3 at least of the peripheral edge portion of a nozzle hole portion 2 in a chamber body 7 made of heat resistant steel, a re-melt treatment layer 8 is formed which is treated using high-density energy with uniformly fine organization and less amount of carbon than the heat resistant steel of base material. As a result, the chamber body 7 is certainly prevented from dropping out of a cylinder head due to transformation and at the same time can be formed as a chamber of satisfactory durability with the nozzle hole portion 2 restrained from being involved in crack.

摘要： PURPOSE:To manufacture aux. combustion chamber simply, easily, and uncostly by forming a blocking part which encloses at least part of one end or both of a hole, at the time of precision casting in such a way as consolidated with a coarse work for chamber. CONSTITUTION:A coarse work 1 for chamber made of austenite type heat- resistant steel having eaves-shaped blocking parts 4 at the ends of a hole 3A is prepared through precision casting. Therein casting material 5 within the hole 3A remains approx. perfectly even after sand shakeoff process. Then the portions 6A, 6B as acute angle part of the jet are subjected to re-melting process by means of TIG arc. The remaining blocking parts 4 are removed in the finish process. Thus existence of the casting material 5 within the hole 3A allows formation of a layer turned into alloy while the shape of the hole 3A is kept as it was even under the condition that high-density energy 7 is impressed at the time of re-melting process. This enables manufacturing coarse works 1 for chamber simply. easily, and uncostly.

摘要： PROBLEM TO BE SOLVED: To provide a torsion bar made of a titanium alloy consisting of a titanium alloy having a low Young's modulus, high strength and high elastic deformability. SOLUTION: The torsion bar made of a titanium alloy at least comprises the group Va (vanadium group) element(s) and titanium (Ti) as the main component. As for stress to be applied, within an elastic deformation region in the range from 0 to a tensile elastic limit strength defined as a stress when permanent strain truly reaches 0.2% by a tensile test, the tilt of a tangent on a stress-strain diagram obtained by the tensile test reduces in accordance with the increase of the stress.

摘要： PROBLEM TO BE SOLVED: To provide a powder compaction process by which active metal powder can be compacted under high pressure.
SOLUTION: The powder compaction process comprises the steps of: applying a higher fatty acid-based lubricant to the inner surface of a die; filling a raw material powder whose major component is an active metallic element into the die after the application step; compacting the raw material powder after the filling step by warm pressing to make a green compact; and ejecting the green compact after the compaction step from the die. The resultant green compact has high density. By this procedure, the active metal powder composed of the active metallic elements, such as Ti and Al, can be pressed under high pressure without causing galling etc. at the inner surface of the die, and the green compact having high density which has not been available conventionally can be obtained.
