This steel is subjected to recrystallization annealing at the temp. above the Ac1 point, then to force air cooling down to an Ar1-600 deg.C temp. range; thereafter, the steel is quickly cooled at >=100 deg.C/sec cooling rate to form the composite structure consisting of a ferrite phase and the low temp. transformation forming phase. The steel is thereafter subjected to the overaging treatment at 350-600 deg.C in such a manner that the ratio of the hardness Hv(L) of the low temp. transformation forming phase to the hardness Hv(alpha) of the ferrite determined by the equations I, II satisfies the equation III. In the equation, the element symbols denote the contents (weight %) of said elements in the steel; ToA denotes the overaging treatment temp.

IPC: G01N29/04
Filed: 1985-06-17
Abstract: PURPOSE:To decide directly whether adhesion is in a state in danger of generation of a crack or not in a short time by making a scan on a material to be inspected and detecting its external edge shape, and performing flaw detection only at the peripheral part along the external edge of the detected material to be inspected. CONSTITUTION:When the strength of the adhesion boundary surface of the material to be inspected, such as an IC and an LSI, where a chip 5 is adhered onto a board 6 is evaluated, a contactor 1 is set at an optional point P of the chip 5. Then, a scan is made in an X and a Y direction to find the surface echo of the chip 5. This surface echo forms a trapezoidal shape rising while having its center at the external edge of the chip 5, so the external edge shape of the chip 5 is detected by fining -6dB of the surface echo level. Then, flaw detection is performed by an automatic ultrasonic flaw detecting method only at the peripheral part of the object material along the external edge of the detected object material to grasp the adhesion and nonadhesion state of the adhesion surface of the peripheral part, and the ratio of the adhesion and nonadhesion surfaces is compared with an evaluation threshold value to device where the chip is acceptable or not.
