What is the correlation between the interface structure, constituent properties and strength-toughness tradeoff in different biological materials? Further explorations are still needed to uncover these enigmas resulted from natural evolution. To date, the shear lag model and its extensions have become the...
There is a strength and fracture toughness tradeoff in nanoceramic composite. The strength varies reciprocally with the grain size whereas the toughness contributed by compressive residual stress increases with the dimension of the second phase. In this work, a novel duplex microstructure with ...
Engineering materials exhibit an undesirable tradeoff between strength and resistance to crack propagation (fracture toughness). Here we demonstrate how this tradeoff can be circumvented by thermo-mechanical processing that produces a partially recrystallized, heterogeneous microstructure. An equimolar CrCoNi ...
At the fundamental level, their current research demonstrates that the tradeoff between strength and fracture toughness, as commonly perceived for conventional alloys, may be evaded in chemically complex alloys through the formation of hierarchical eutectic structures.doi:10.1002/adem.201801060...
