STUDYING THE EFFECT OF PLASTIC DEFORMATION ON THE MECHANICAL AND MAGNETIC CHARACTERISTICS OF HIGH-STRENGTH BIMETAL MATERIALS INTENDED FOR USE IN THE ARCTIC CLIMATE

The paper presents the results of investigation of the mechanical and magnetic properties of bimetal high-strength materials, produced by explosion welding and operating under arctic climate conditions, depending on the magnitude of cold rolling reduction. The main layer in the materials is made of the 15KhN4MDF high-strength steel and the clad layers are constituted by two different corrosion-resistant steels, 08Kh18N10 and 04Kh20N6G11M2AFB, with different austenite stabilities. Cold rolling with different reduction ratios is performed in order to simulate the effect of plastic deformation on the properties of high-strength bimetal materials and to estimate the applicability of nondestructive magnetic methods to the diagnostics of the state of such materials, as well as of their individual constituents. The mechanical and magnetic properties of the constituents (the hull steel and the corrosion-resistant steels with different austenite stabilities) are compared with those of the bimetals. It is reported that the values of microhardness near the welded joint increase in all the bimetals under investigation. The dependences of the strength characteristics on the values of the reduction ratio have been obtained. Informative magnetic parameters, uniquely varying with an increase in the rolling ratio, have been established. These parameters could later be used to develop nondestructive methods of testing the state of bimetallic materials under operation.
