本文研究了含有大量应变诱发马氏体（ε ′）的奥氏体不锈钢（SUS 304）喷丸诱发逆相变的温度依赖性。当喷丸温度高于100 ℃时，喷丸表面奥氏体（γ）的体积分数增加。这表明喷丸处理发生了逆相变。此外，逆相变产生的γ的量随着加工温度的升高而增加。因此，发现SUS304钢经喷丸处理后的逆相变行为取决于处理温度。
Temperature dependence of the reverse transformation induced by shot-peening has been investigated for austenitic stainless steel (SUS 304) containing large amount of strain-induced martensite (α’). When the SUS 304 specimen is shot-peened under higher temperature than 100oC, the volume fraction of austenite (γ) on the peened surface is increased. This indicates that the reverse transformation is occurred by the shot-peening. Furthermore, the amount of the γ generated by the reverse transformation is increased as the processing temperature increases. Hence, it is found that the reverse transformation behavior of the SUS 304 steel by the shot-peening depends on the processing temperature.
