Structure of the heat-affected zone in weldments of steel 24Kh2NMFA

Metal Science and Heat Treatment, 1977
1. With multipass welding of rotor steel 24Kh2NMFA granular bainite is formed in the HAZ. The matrix of the bainite is the α solid solution formed by martensitic kinetics; small areas of granular or elongated form evenly distributed in the matrix consist of martensite and retained austenite. 2.

Development of an intelligent model to optimize heat-affected zone, kerf, and roughness in 309 stainless steel plasma cutting by using experimental results

Materials and Manufacturing Processes, 2018
Plasma cutting is an effective way to cut hard metals. In this process, three output parameters cutting width (kerf), surface roughness (Ra) and heat-affected zone (HAZ) are critical factors which affect the quality and efficiency of the cutting. In this

Prediction of hardness distribution in steel heat affected zone

Science and Technology of Welding and Joining, 1999
A practical method to predict the heat affected zone (HAZ) hardness distribution was studied by considering the effects of prior austenite grain size and tempering on hardenability. For conventionally rolled and thermomechanically processed steels (400–490 MPa grade steels), the hardness distribution between the fusion and Ac3 lines can be fairly well

Microfissuring of Alloy 718 in the Weld Heat-Affected Zone

JOM, 1988
Alloy 718 suffers from microfissuring in the weld heat-affected zone, and compositional, structural and mechanistic causes of this defect have been examined. Both bulk sulfur and bulk carbon increase microfissuring, and heat treatments typical ofhomogenization, solution annealing and age hardening reveal that microfissuring is sensitive to the ...

PWSCC Susceptibility in Heat Affected Zones of Alloy 600

2011
The recent field experience and several experimental results have shown the possible deleterious effect of a heat affected zone (HAZ) induced by welding on the susceptibility to the stress corrosion cracking (SCC) of Alloy 600 of bottom penetrations exposed to primary water of PWRs.
