σ-phase precipitation in weld metal of austenitic stainless steels and its effect on properties

Hanjie xuebao
Low-temperature conditions necessitate high toughness in the welded joints of austenitic stainless steel structures. However, the impact toughness of the weld metal decreases significantly when using electrodes developed for SMAW under such conditions ...

Achieving exceptional strength-low temperature toughness synergy in the microalloyed medium carbon steel via layered heterogeneous structure

Materials & Design
The further advancement of microalloyed medium carbon steels is often limited by low-temperature toughness instability. A microalloyed medium carbon steel with both strength and low-temperature toughness was produced through a warm rolling and short-time

A Wireless, Passive Multimodal Wearable Sensor With Decoupled Sensing Capabilities

Advanced Materials, EarlyView.
A wireless passive multimodal electronic skin is presented for the simultaneous perception of pressure, humidity, and odor through a frequency‐divided LC resonator array. The decoupled sensing architecture suppresses cross‐interference and enables independent signal readout under superimposed stimuli while maintaining high stability.

Effect of Welding Position on the Low-Temperature Impact Toughness of Weld Metal in High-Strength Low-Alloy Steel

Journal of Welding and Joining
The effect of welding position on the mechanical properties of high-strength low-alloy steel weld metals was investigated with an emphasis on low-temperature impact toughness. Welding was performed in horizontal (2G) and vertical-up (3G) positions using two filler wires with different alloying element contents.
