| Abstract [eng] |
The article deals with the investigation of transformation plasticity phenomenon of low carbon high chromium steel 0.19C-12.71Cr during 1 hour bending at 520 degrees C and 650 degrees C temperatures after long-lasting ageing. One part of steel specimens was bent after hardening, another part was hardened, aged at 520 degrees C or 650 degrees C temperatures for 1, 5, 10, 24, 48, 120 or 240 hours and then was bent during tempering at the same temperature. During the test of bending, the curve of plastic deflection of the steel specimen was obtained and remained plastic deflection after bending test was measured. After bending experiment, some steel specimens were picked up for X-ray analysis for determination of carbide particles type, its' parameter of lattice and content of chromium in it. The results obtained have allowed going more into analysis of phenomenon of transformation plasticity of this steel type, evolution of carbide particles and influence of bending stress on transformations of tempering. |
