Structure and phase composition of weld seams in maraging steel

Conclusions

  1. 1.

    The structure and phase composition of welds made by electroslag welding were investigated after different heat treatments.

  2. 2.

    The possibility of grain refining of the heat-affected zone and the weld seam was shown.

  3. 3.

    The chemical microheterogeneity and phase heterogeneity of the weld seam and heat-affected zone were investigated. The existence of segregation heterogeneity is responsible for the difference in tendency to precipitation hardening in different sections of the seam, and the phase heterogeneity reduces the effect of aging.

  4. 4.

    The phase heterogeneity is eliminated by heating in the austenitic range, and homogenization also eliminates segregation heterogeneity to a considerable extent.
