An order of magnitude decrease (from 16.0 × 10-4 to 4.1 × 10-4% h-1) in steady-state creep rate was observed in the fine-grained heat-affected zone (HAZ) of a Cr-Mo steel weld by the reduction of the pre-weld tempering temperature from 760 °C (HTT...

Elastic moduli in steel alloys with different martensitic start temperatures were measured during the cooling cycle by using the ultrasonic pulse sing-around method. Our findings show that the shear modulus governs austenite stability prior to mar...
