As base metals (BMs), plates of 5-mm-thick low-alloyed ultra-high-strength carbon steel (LA-
UHSS) with a tensile strength of 1.3 GPa and 5-mm-thick 316L austenitic stainless steel …

In this study, a post-weld heat treatment (PWHT) at a high temperature of 700° C for 10 min
was proposed to significantly improve the mechanical performance of dissimilar laser …

Local vacuum electron beam welding (LVEBW) breaks through the limit of vacuum chamber
and can be flexibly proceeded in more working conditions. Using LVEBW to substitute …

The inner tank is the core weldment of the electric water heater (EWH). During service,
leakage often occurs at the welds of the inner tank due to stress concentration. Reducing the …

In this study, the influence of building orientation of additively manufactured 316L stainless
steel (SS) welded joints was investigated. Laser powder bed fusion (LPBF) technique was …

Morphology and distribution of intermetallic compounds in the heat-affected zone (HAZ) are
easily altered during welding thermal cycles, contributing to the softening of the HAZ …

The mechanical performance and stretch formability of dissimilar butt joints between
medium-Mn stainless steel (MMn-SS) and high-strength carbon steel (HS-CS) processed by …

This study highlights the strengthening mechanisms observed during the metal joining of
high-strength grade steels (Al-TRIP and Si-TRIP) by providing a concise investigation of …

The study aims to investigate the influence of environmental media on the friction and wear
behavior of low-alloy wear-resistant steels and to provide practical references for their …

In this paper, a disk laser welding was developed to join 3-mm thin-Sect. 30Cr3 ultra-high-
strength steel which was widely used in aerospace. The microstructure and mechanical …
