For the purpose of reducing measuring time, the Rapid Analyzer of X-ray Stress (RAXS), installed with double Position Sensitive Proportional Counter (PSPC), was deveroped.
The divergent slit employded was parallel beam slit. Some experimental approches, in which the influence of insident beam width ranges from 1 to 5mm, with both X-Ray line profile broadness and X-Ray strain sensitivity was studied, showed that there are no differences of those values between 5mm and 1mm beam width.
It was also found that the apparent stress caused by the misalignment to sample, was about 2.5Kgf/mm2 per 1mm.
The measurement by means of Schaal method can be made in about 5sec., and this means that the measurement time can be reduced to one-two hundredth to one-fourhundredth, comparing with the conventional equipment.
This equipment has already been installed in NHK Spring Co. Ltd., for measuring the residual stress of automotive springs.
