Here we show that the Discrete Element Method (DEM) can account for reinforcement mechanisms such as microcracking and crack deflection, and quantitatively assess strength, initiation toughness and crack growth toughness. Two approaches are studied to enhance strength and toughness of nacre-like ceramics...
High strength steels exhibit superior mechanical properties due to the unique microstructure, which successfully solves the drawback of the inevitable strength-toughness trade-off that occurs in traditional alloys. Here we investigated the effect of matrix and precipitates on mechanical properties of Cr–...

The strength–ductility trade-off has been a long-standing dilemma in materials science. This has limited the potential of many structural materials, steels in particular. Here we report a way of enhancing the strength of twinning-induced plasticity steel at no ductility trade-off. After applying...

ductility, or toughness, will undermine one or more of the others. For example, an increase in strength will inevitably make the metal more brittle (known as the strength-toughness trade-off); or less flexible to be extended or elongated into different shapes. (strength-d...
The Relationship between Strength and Toughness in Tempered Steel: Trade-Off or Invariable? Two different types of strength‐toughness relations are investigated in tempered steel (tempered at 25–420 °C). It is found that there is a trade﹐ff re... Li, He-Fei,Duan, Qi-Qiang,P Zhang,....

Strength and toughness are a couple of paradox as similar as strength-ductility trade-off in homogenous materials, body-centered-cubic steels in particular. Here we report a simple way to get ultrahigh toughness without sacrificing strength. By simple alloying design and hot rolling the 5Mn3Al stee...
