Report 1. The effect of single-overload conditions [Elektronische Daten] [V. Troshchenko, V. Pokrovskii, V. Podkol'zin, P. Yasnii] Investigations were carried out into the effect of the temperature-force parameters of preliminary loading (PL) on the resistance to brittle failure in static loading of 15Kh2MFA heat-resisting vessel steel in two structural conditions and the embrittled metal of a welded joint in 10KhMFT steel. The results show that the brittle-fracture resistance increases rapidly after preliminary loading in materials with a high yield limit. It is shown possible to utilize the effect of preliminary loading directly during hydraulic tests of a vessel of a power plant reactor. It is also shown that the effect of PL operates only at relatively long crack lengths. The results show that the main factor determining the effect of PL is blunting of the crack tip after preliminary loading, whereas the residual compressive stresses, formed in the region of the crack tip in the loading stage, have no marked effect on the PL effect.
