Fatigue life of materials claded with the method of explosive welding
Journal Title: Bulletin of the Military University of Technology - Year 2018, Vol 67, Issue 2
Abstract
This paper describes the comparison of fatigue life on bending of two claded materials with the base material. The base material was the carbon steel P3335NH of the thickness of 10 mm and the clad materials was austenitic steels 254SMO and 316L. As a part of the work, ultrasonic testing of static tests such as tensile tests, shear tests, bending tests and impact tests were performed. The hardness distribution tests in the cross-section of the sample was subsequently carried out. Last tests were the cyclic bending tests at four different loads. Surveys show that the plates are connected to the entire surface with the exclusion of technological margins of approximately 30 mm per side and the detonation initiation point, which, as a rule, is always a non-connected area. Hardness distribution tests shown that the explosive plating process has resulted in an increase in the hardness of materials near the joint line. The bending studies show that the highest fatigue life is the same as the base material compared to the cladding materials. For each sample, the crack initiation always started in the base material.
