13(HRL) when adhesive weight is 25% and maximal impact strength is 4. 68kJ/ m2 when adhesive weight is 28%. Hardness plays a main role when adhesive weight is lower, on the other hand, impact toughness plays a major role when adhesive weight is higher.关键词: frictional materials impact...
athe effect of thermocycling on fracture toughness and hardness of different core build up materials. thermocycling的不同的核心组合材料的作用在破裂韧性和坚硬。[translate]
a The values of mechanical properties (hardness, bending strength, impact toughness and fracture tough-ness) are shown in Table IV for specimens treated by the procedures shown in Table II. It can be seen that the hardness values of specimens with different microstructures are all higher than HR...

The fracture toughness of hard biomaterials, such as nacre, bovine hoof wall and beetle cuticle, is associated with fibrous or lamellar structures that deflect or stop growing cracks. Their hardness and reduced modulus were measured by using a nanoindenter in this paper. Micro/nanoscale cracks were...
This is the most popular heat treatment since the outcome is predictable. Tempering is used across various types of steel to balance hardness and toughness, making the steel material less brittle after quenching. Quenched steel is reheated and chilled to temperatures below the lower critical point....
At this point, bulk mechanical properties such as the Young’s modulus, fracture stress and toughness determine how the material will respond under the multiaxial loading occurring by the action of the teeth [26]. These mechanical properties are reported to also influence mastication parameters such...
In the present work we have investigated the effect of four different tempering temperatures of vacuum and cryogenically treated ESR AISI M2 high-speed steel on the resulting combinations of microstructure, hardness and toughness and their effect on the wear mechanisms at different loads. The results...
