Effects of temperature on the microstructural evolution and mechanical properties of copper − bearing medium manganese steel during tempering

Materials & Design
This work introduced the effects of higher tempering temperatures on the microstructural evolution of Cu − bearing medium Mn steel. After quenching steel at 860 °C for 1 h, it was tempered at 600, 640, and 670 °C for 2 h.

A newly developed snow vehicle (SM100S) for Antarctica III. Low temperature toughness of the welded joints of the structural steel

Antarctic Record, 1992
For the purpose of developing a new snow vehicle car (common use at temperature about -50℃) for the deep ice coring project at Dome Fuji, East Antarctica, the low temperature toughness of the welded joints of structural steel was investigated.

Highly Entangled Bottlebrush Polymer Networks

Advanced Materials, EarlyView.
Bottlebrush polymers are difficult to entangle, enabling ultrasoft yet brittle networks. We report highly entangled bottlebrush elastomers that remain ultrasoft (∼1 kPa) yet stretch to ∼1800% and exhibit exceptional fatigue resistance. Their intrinsic fatigue strength—fatigue threshold normalized by modulus—surpasses that of highly entangled linear ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Study on Impact Toughness and Fracture Characteristics of N80 Steel Oil Casing at Low Temperature

Cailiao Baohu, 2023
For clarifying the toughness change rules of N80 steel for oil casing under low temperature conditions, the oscillometric shock performance tests were conducted on N80 steel oil casing materials at different temperatures (25, 0, -20, and -40 ℃) using an oscilloscope impact meter.

Magnetic DNA Origami Nanorotors

Advanced Materials, EarlyView.
Magnetic actuation is a powerful and broadly applicable actuation mechanism due to its programmability and compatibility with biological entities. Here we demonstrate magnetic DNA origami nanorotors (MADONAs) by assembling magnetic nanocubes on DNA origami.

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.
