Cavitation resistance of cold-worked steels and copper

We have studied the cavitation resistance of 15Kh11MF steel and copper after low-temperature (∼ 300 K) deformation by rolling, program loading, ultrasonic treatment, and equal-channel multiangle pressing. We have established that the cavitation resistance grows by no more than 50% as a result of ultrasonic treatment, program loading, and rolling at 77 K of 15Kh11MF steel and equal-channel multiangle pressing of M1 copper. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 43, No. 3, pp. 89–92, May–June, 2007.
