Evidence for mechanical softening-hardening dual anomaly in transition metals from shock-compressed vanadium

Observation of a New Mechanism Balancing Hardening and Softening in Metals

Assessment of Heavy Metals Transition (Pb, Ni and Vanadium) In Hur Al-Azim Wetland Food Chain

Heavy metals are one of the most important organic pollutants in the environment due to human activities in the environment. This study was carried out to investigate heavy metals in 7 stations of Hur al-Azim wetland in the spring of 2018. The statistical population for measuring heavy metals such as Ni, Pb and vanadium with 3 repetitions included 21 sediment samples, 21 water samples, 21 Phrag...

Softening up on the hardening hypothesis.

The hardening hypothesis has intuitive and common sense appeal: in jurisdictions that have implemented evidence-based tobacco control policies, the smokers who have a relatively easy time quitting will quit, and as the future unfolds there will be an increasing proportion of remaining smokers who cannot quit and are more resistant to quitting than smokers in the past. In this context, ‘hardenin...

Improvement of Mechanical Properties and Work-Hardening Behavior of Intercritically Annealed Dual Phase Steel

The effect of the initial microstructure and intercritical annealing on mechanical properties and work-hardening response of a high-formability low carbon steel were studied. The work-hardening analysis was based on the modified Crussard–Jaoul method. The ferritic-pearlitic sheets showed low strength and high total elongation with the appearance of the yield point phenomenon. The occurrence of ...

Network Topology in Soft Gels: Hardening and Softening Materials.

The structural complexity of soft gels is at the origin of a versatile mechanical response that allows for large deformation, controlled elastic recovery, and toughness in the same material. A limit to exploiting the potential of such materials is the insufficient fundamental understanding of the microstructural origin of the bulk mechanical properties. Here we investigate the role of the netwo...
