PROBLEM TO BE SOLVED: To provide a metal structure product and an iron structure product excellent in resistance to cracking in an environment in which the material experiences a stress and is in contact with a liquid metal, namely, resistance to liquid metal embrittlement and to provide a method for producing them.
SOLUTION: The 50 μm thick layer underlying the surface of a site where the liquid metal embrittlement of a metal structure product or an iron structure article is problematic is made from ultrafine crystal grains. The longer axis of the ultrafine crystal grains or old austenite grains is substantially parallel with the surface. Desirably, the ratio of the length in the length direction to that in the breadth direction in the crystal grains or the old austenite grains is 5 or higher. This is attained by subjecting the surface of a site where the liquid metal embrittlement of the iron structure product is problematic to an ultrasonic impact treatment. Desirably, the ultrasonic impact treatment is followed by a quality assurance inspection for inspecting whether or not the layer underlying the surface to a depth of 50 μm has undergone plastic deformation.

PROBLEM TO BE SOLVED: To provide a method for highly durable identification marking on a component without practically changing the physical shape of the component. SOLUTION: Durable component-marking is realized by local modification on the surface of a material. The property in the specific surface regions (106, 110) of the component is changed without practically changing the physical shape of the component. By arranging these changes in a consistent pattern, the method for highly durable identification marking can be obtained. After that, by detecting and interpreting the consistent pattern, the original identification mark can be found. Different from labeling, ink marking, stamping, or etching, the many surface modification on the surface, or the modification in the vicinity of the surface is not necessarily seen by the human eyes. Therefore, this method contains (1) a method for surface modification, (2) a method for enhancing readout ability and accuracy in the readout of coded data, and (3) a method for deciding the position of the surface change. |

PURPOSE: To produce jet engines or the like by producing superalloy cast articles by casting from a hardly castable high melting temp. superalloy compsn., thereby eliminating the need for lines or the like for protection against the high temp. of combustion gases and reducing the weight. CONSTITUTION: A product is cast from the uncastable high melting temp. superalloy. The temporary defect 34 existing in the product and the metallic portion 40 around the same then ground away to form an excised space. A filler metal having the same compsn. as the compsn. of the product is filled by welding or the like into the excised space. If there is a defect in the filler metal, the defect is excised and the oxide on the surface of the filler metal is removed. A mixture composed of a binder and cladding powder is added to the surface of the filler metal and the product is subjected to a heat treatment, by which the binder is removed and the cladding powder is melted and solidified. The product is subjected to high-temp. isostatic compression. The cladding powder is a mixture composed of the particle of the high melting temp. superalloy and a low melting temp. superalloy. As a result, the product reduced in the weight while maintaining the high-temp. performance is obtd. |

PURPOSE: To provide a process for identifying, evaluating and removing the microsrhinkage of investment cast superalloy parts and the parts produced by this process.
CONSTITUTION: The parts which do not have the detrimental microsrhinkage and enable the longer life at the existing stress level or are usable at a higher repetitive stress are produced in this process. For this purpose, the parts are first subjected to a hot isostatic pressing treatment, by which the microsrhinkage under the surface not communicating with the front surface is removed. Next, the parts are immersed into an acid soln. for the time sufficient for uniformly removing at least about 0.005 inch on the initial cast surface in order to microscopically expose the microsrhinkage near the surface communicating with the front surface. The thus exposed microsrhinkage is evaluated as to be permissible or to be removed by a standard non-destructive inspection method.

PURPOSE: To provide a method for obtaining effective stress relieving by mechanically applying periodical vibration energy to an object, monitoring the attenuation effect thereof, identifying the peaks of plural higher harmonic vibrations and applying vibration energy to the object at the frequencies corresponding to the fractional harmonic frequencies of these peaks.
CONSTITUTION: The stresses of a beam 10 which is the metal to be the object are relieved. The periodical vibration energy is first mechanically applied by a vibrator 16 on the object (beam) 10 in a test frequency range. The attenuation effect of the energy flowing into the object 10 is monitored as the function of the frequency. The absorption peaks of the plural higher harmonic vibrations consisting of the peaks of the resonance absorption of the respective plural vibrations are identified by an electron controller 18. The mechanical periodical vibration energy is applied by using the vibrator 16, an electronic controller 18 and a control means 22 on the object for the substantial time at the specified frequencies corresponding to the fractional harmonic frequencies of the absorption peaks of the harmonic vibrations. As a result, the method for stress relieving of a wide range of metallic alloys including both soft and hard alloys is provided.

PURPOSE: To obtain an amorphous metal having an optionally shaped amorphous region by irradiating an objective metal with an electron beam having high penetrating power to introduce lattice defects, and controlling the concn. of the lattice defects.
CONSTITUTION: An intermetallic compd. such as NiTi and Fe
2Ti is irradiated with a high energy electron beam having energy sufficient to damage the compd. When the irradiation is carried out, the density of the electron beam is kept at a value high than the critical value determined by an objective metal, and the irradiation temp. is simultaneously controlled at a temp. below the critical temp. determined by the objective metal and the density of the electron beam thereof. Under said condition, lattice defects, introduced into the inside of the metal by the damaging action of the irradiation are gradually accumulated, and the concn. thereof is increased with irradiating time. When said concn. reaches the fixed value determined by the objective metal, the irradiated metal is transformed into an amorphous metal.
