| 摘 要： | The maximum thermal stress and stress concentration zones of iron/TiC cermet joint during cooling were studied inthis paper. The results showed that the shear stress on iron/TiC cermet joint concentrates on the interface tip andthe maximum shear stress appears on the left tip of iron/TiZrNiCu interface. Positive tensile stress on TiC cermetundersurface concentrates on both sides of TiC cermet and its value decreases during cooling. Negative tensile stresson TiC cermet undersurface concentrates on the center of TiC cermet and its value increases during cooling. Brazingtemperature has little effect on the development and maximum thermal stress.

| Abstract: | The maximum thermal stress and stress concentration zones of iron/TiC cermet joint during cooling were studied in this paper. The results showed that the shear stress on iron/TiC cermet joint concentrates on the interface tip and the maximum shear stress appears on the left tip of iron/TiZrNiCu interlace. Positive tensile stress on TiC cermet undersurface concentrates on both sides of TiC cermet and its value decreases during cooling. Negative tensile stress on TiC cermet undersurface concentrates on the center of TiC cermet and its value increases during cooling. Brazing temperature has little effect on the development and maximum thermal stress. |
