Effects of PWHT on the microstructure and mechanical properties of ERNiCrFe-7 all-weld metal

, 2015
The effects on the microstructure and room temperature mechanical properties of the nickel-based filler metal ERNiCrFe-7 due to a post weld heat treatment (PWHT) at 610 °C have been studied. It was shown that PWHT caused an increase in yield strength and

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects

Strain, Volume 61, Issue 2, April 2025.
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.

Tuning residual stresses in welded structures by exploiting bio‐inspired suture interfaces

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4560-4572, December 2024.
Abstract Nature offers a valuable source of inspiration when designing optimized structures. For instance, when two or more shells are joined during growth processes, Nature prefers to exploit interlocking paradigms to enhance the strength of the bond—cranial sutures are one example.

Effects of PWHT on the Hardness and Fractured Microstructure of IS-103Cr1 Welded Joint

Journal of Material Science & Engineering, 2016
During the welding process change of chemical and physical reactions due to the flow of heat in the weldments are varied with respect to rate of cooling time and weld axis. In the dissimilar welded joints, at the welded portion it can be exist in more than one crystalline form and the carbon atom is only 1/30th size of the iron atom.

Improving Mechanical Properties of PVPPA Welded Joints of 7075 Aluminum Alloy by PWHT [PDF]

Materials, 2018
In this study, 7075 aluminum alloy with a thickness of 10 mm was successfully welded with no obvious defects by pulsed variable polarity plasma arc (PVPPA) welding. The mechanical properties of PVPPA welded joints have been researched by post weld heat treatment (PWHT).
