Notes:
Precipitation phenomena in an austenitic stainless steel, SUS316L cold-rolled withvarious reduction rates were studied by transmission electron microscopy and synchrotron radiationdiffractmetry. After the aging at 573 K for 15000 h, two of precipitates were observed, whichwere identified as M7C3 and M23C6 by SR diffraction and electro diffraction measurements. Theprecipitates M7C3 were formed at both innergranular and grain boundary, while the precipitateM23C6 was formed at innergranular. The precipitation was promoted with increasing cold rollingreduction. Also segregation of phosphorous was detected along grain boundaries. Besides, theresidual stresses were measured with side inclination method using a synchrotron radiation facility,SPring-8. The residual stresses were increased with increasing the cold rolling reduction rate
