Abstract
In this study, the post-weld heat treatment (PWHT) cracking susceptibility in the heat affected zone (HAZ) of martensitic 10Cr steel was evaluated. The specimens taken from the 10Cr steel were thermally cycled using a Gleeble to simulate HAZ 1 (δ-ferrite) and HAZ 2 (single phase, γ). HAZ 2 had martensite.....

Abstract
In this study, the effects of hot forging and heat treatment (quenching and tempering) of cast Cr alloy steel on the microstructures and mechanical properties were investigated. The hot forging was performed at a compressive ratio 0.5 at 1,250
