摘要： PURPOSE:To manufacture a material having high magnetic flux density at a low cost without adding any expensive element by depositing (Si, Al)N in a silicon steel sheet before finish annealing and by causing secondary recrystallization by the function of the deposit. CONSTITUTION:A silicon steel slab contg. 1.5-4.5% Si is hot rolled, annealed and cold rolled to the final thickness. The resulting steel sheet is subjected to decarburization annealing and after (Si, Al)N is deposited in the steel sheet by nitriding or other treatment, the steel sheet is subjected to finish annealing at a high temp. to cause secondary recrystallization by the function of the deposited (Si, Al)N. By this method, a grain-oriented silicon steel sheet having high magnetic flux density can stably be manufactured.

摘要： PURPOSE:To precisely and easily identify a material by arithmetically forming the model diffraction pattern by an estimated material, and displaying this model diffraction pattern and the measured pattern of electron diffraction pattern overlapped with one over the other. CONSTITUTION:The coordinate of each dot of an electron diffraction pattern recorded on a photograph or imaging plate is read, for example, by coordinate detection by image processing, or directly by use of a magnifying glass with micrometer or a digitizer 1, and inputted to an arithmetic control means 2. The arithmetic control means 2 reads the data of an estimated material estimated by elemental analysis from a disc memory 3 and conducts forming processing of model diffraction pattern to display the obtained model diffraction pattern and the measured net pattern of electron diffraction pattern overlapped with one over the other on a CRT 4. Thus, precise substance identification can be easily and rapidly performed.

摘要： PURPOSE: To provide a titled separating agent for annealing which satisfies simultaneously the stabilization of the secondary recrystallization and the improvement in a forsterite insulating film characteristic in the stage of finish annealing by incorporating the ferromanganese nitride consisting of Mn, Fe and N and expressed by the specific formula at a specific ratio with respect to magnesia.
CONSTITUTION: The titled separating agent for annealing is obtd. by incorporating the ferromanganese nitride or manganese nitride consisting of the compsn. of which the relation of Mn, Fe and N is expressed by the formula (Mn
1-x )N
y and the values (x) and (y) are in the region enclosed of the points A, B, C, D at 0.2W20pts.wt. by 100pts.wt. the magnesia. The nitrogen cracking temp. of the separating agent is about 600W900°C. The agent is effective for increasing the nitrogen partial pressure in the atmosphere from the initial period of finish annealing and provides the higher effect than heretofore in a wide temp. region to make uniform the nitrogen partial pressure in the transverse direction of a coil. Mn
1-x Fe
x changes to an oxide after the release of nitrogen and contributes to the acceleration of the reaction to form forsterite. The grain size thereof is about ≤0.5μ and the film having excellent mechanical properties is obtd.

摘要： PURPOSE: To prevent the cracking of a carbon steel or a low alloy steel contg. B and S adjusted to a specified amount or below and to enhance the hardenability by hardening the steel from a specified temp. or above.
CONSTITUTION: A carbon steel or a low alloy steel contg. 0.00005W0.0005% B, C and S adjusted to ≤0.001% as well as Si, Mn, P, Cr, etc. is refined. The steel is hot rolled, treated at an austenitizing temp. above 800°C, and quench-hardened. Since the amount of B added to provide hardenability is reduced as compared to a conventional content, CC ingot cracking, hot cracking and weld cracking due to excess B are prevented.
