【摘要】 本文在18-8型不锈钢中测出了深冷诱发马氏体的一个内耗峰。当测量频率为2.86,4.0和500Hz时峰的温度相应为300,306和1360K,该峰的激活能和频率因子分别为0.92ev和6.3×10¹⁵秒^-1,本文证明,此类钢的两种马氏体——形变诱发马氏体和深冷诱发马氏体——具有相同的驰予现象和同一种Snoek峰。更多还原

【Abstract】 An internal friction peak which is considered to be Snoek peak due todeep cooling martensite in 18-8 type stainless steel has been found. Thepeak temperature is 300, 306 and 360k at measurement frequency of about2.96, 4.0 and 500H_z, respectively. The activation energy of the peak is0 .92 ev, and the frequency factor is 6.3×10¹⁵ S^-1 . The present work showsthat there is identical relaxationp henomenoh and the same Snoek paekfor both the two kinds of martensite, the deep cooling induced martensiteand the stress induced martensite, in 18-8 type steel.更多还原
