残留オーステナイト相の応力測定に関するX線的研究

Since retained austenite particles have great influence upon the mechanical properties of hardened steel, it is very important to know internal stresses in the retained austenite phase. However, the retained austenite diffraction line is too weak, so that we have a very great difficulty to measure the stresses. In this paper, applying the all over angles method, we measured the internal tresses of martensite and retained austenite in hardened steels. Moreover x-ray elastic constants of each phase were calculated.
