Fracture Toughness

Single-phase body-centered cubic (bcc) refractory medium- or high-entropy alloys can retain compressive strength at elevated temperatures but suffer from extremely low tensile ductility and fracture toughness. We examined the strength and fracture ...

Hydrogen bond engineering can convey stretchability, toughness and self-healing properties to materials, although enhancement effects of conventional hydrogen bonds is limiting due to their weak interaction strength. For instance, organisms can withstand extreme conditions due to strong hydrogen bond-based interactions induced by trehalose. In a new report now published in Science Advances, Zilong Han and a team of…

After Sunday night's incredible, shocking episode of "Succession," fans are rallying for the actress to win her first Emmy for her stunning performance. And they're right!

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ductile—which, in materials science, means highly malleable—and impressively strong (meaning it resists permanent deformation), its strength and ductility improve as it gets colder. This runs counter to most other materials…

CrCoNi-based alloys have very high fracture toughness at 20 kelvin.

A research group led by Prof. Wang Zhenyang and Zhang Shudong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has developed synergistic aerogel materials with high temperature resistance, mechanical strength and thermal insulation performance.

/PRNewswire-PRWeb/ -- A Hot Isostatic Press (HIP) from Quintus Technologies is at the heart of Wallwork Group's new HIP Centre stated to open in Bury, North...

Dr. Amir Asadi, an assistant professor in the Department of Engineering Technology and Industrial Distribution at Texas A&M University, is making groundbreaking strides in the field of composite materials. His research explores embedding patterned nanostructures composed of multiple materials into high-performance composites to achieve the desired multifunctionality without sacrificing any other properties. This…

In collaboration with the Institute of Physics at the Chinese Academy of Sciences (IPCAS), researchers from Beijing University of Technology (BJUT) have discovered a new type of grain-interior planar defect in a ceramic phase in TiC doped cemented tungsten carbides.

At the end of 2022, researchers at Lawrence Livermore National Laboratory announced they had observed a net energy gain through nuclear fusion for the very first time. This monumental milestone toward fusion energy represents a huge leap forward in powering our homes and businesses with the carbon-neutral energy source. But converting this scientific achievement into a practical power source also requires new…

A new study reveals the profound properties of a simple metal alloy. Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ductile – which, in materials sci

Mechanical metamaterials are an emerging class of materials primarily governed by their architecture to create lightweight materials with extreme mechanical properties. The functionality of such materials is limited by their tolerance to damage and defects, better known as "fracture toughness." Materials scientists credit the difficulty in part to the manufacture and characterization of a large number of unit…

The mantis shrimp's club uses a built-in vibration shield that filters out damaging shock waves to enable it to strike with bullet-like force without breaking.

A company that emerged from the marine engineering sector holds the secret to the ultra-luxury brand's remarkable material that is as light as plastic, but several times stronger than steel.

The material might just revolutionize modern manufacturing.

Scientists are hard at work considering what kinds of engineering alien probes would need to reach us through interstellar space.

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel. Not only is the metal exceptionally strong and ductile, its properties become enhanced as it gets colder. This runs counter to most other materials in existence.

In recent years, roboticists and material scientists worldwide have been trying to create artificial systems that resemble human body parts and reproduce their functions. These include artificial skins, protective layers that could also enhance the sensing capabilities of robots.

A new design tool for electronics manufacturers could reduce product failures and boost productivity for printed circuit boards

Barium strontium aluminum silicate (BaxSr1−xAl2Si2O8, BSAS) ceramics possess both phase stability and resistance to water vapor corrosion, making them ideal materials for radome technology and electronic packaging. To address the low tolerance of BSAS ceramics to damage and defects, the introduction of nano-reinforcements is an effective approach to enhance their strength and toughness.
