Significance of stacking fault energy in bulk nanostructured materials: Insights from Cu and its binary alloys as model systems
Publication date: Available online 10 November 2018Source: Progress in Materials ScienceAuthor(s): X.H. An, S.D. Wu, Z.G. Wang, Z.F. ZhangAbstractBulk nanostructured (NS) materials processed by severe plastic deformation (SPD) have received considerable attention for several decades. The physical origin of this processing philosophy is to enable substantial grain refinement from a micrometer to a nanoscale level mainly through the activation of fundamental deformation mechanisms: dislocation glide, deformation twinning, and their sophisticated interactions. The formation of nanostructures in NS metallic materials is signif...

Redox-electrolytes for non-flow electrochemical energy storage: a critical review and best practice
Publication date: Available online 30 October 2018Source: Progress in Materials ScienceAuthor(s): Juhan Lee, Pattarachai Srimuk, Simon Fleischmann, Xiao Su, T. Alan Hatton, Volker PresserAbstractOver recent decades, a new type of electric energy storage system has emerged with the principle that the electric charge can be stored not only at the interface between the electrode and the electrolyte but also in the bulk electrolyte by redox activities of the electrolyte itself. Those redox electrolytes are promising for non-flow hybrid energy storage systems, or redox electrolyte-aided hybrid energy storage (REHES) systems; pa...

High Temperature Materials for Heavy Duty Diesel Engines: Historical and Future Trends
Publication date: Available online 24 October 2018Source: Progress in Materials ScienceAuthor(s): Dean Pierce, Allen Haynes, Jeff Hughes, Ron Graves, Phil Maziasz, Govindarajan Muralidharan, Amit Shyam, Ben Wang, Roger England, Claus DanielAbstractHeavy duty (HD) vehicles are projected to be the largest fuel-use subsector in transportation, with current demand for diesel fuel projected to grow 30% by 2040. Historically, a primary strategy for increasing diesel engine efficiency has been to increase peak cylinder pressure (PCP). However, increasing PCP imparts greater mechanical and thermal loads on engine components and ma...

Thermal conductivity of 2D nano-structured boron nitride (BN) and its composites with polymers
Publication date: Available online 24 October 2018Source: Progress in Materials ScienceAuthor(s): Valentina Guerra, Chaoying Wan, Tony McNallyAbstractHigh thermal conductivity, structural stability, good mechanical and anti-oxidant properties makes hexagonal boron nitride (h-BN) a promising functional filler for polymers to produce composite materials where excellent thermal management is required, such as in electronic devices. Theoretical studies have revealed that two dimensional (2D) BN has higher thermal conductivity (up to 400 Wm-1K-1, in-plane) than bulk h-BN due to a reduction in phonon-phonon scattering when scali...

Kinetics of interaction of impurity interstitials with dislocations revisited
Publication date: Available online 22 October 2018Source: Progress in Materials ScienceAuthor(s): J. Svoboda, W. Ecker, V.I. Razumovskiy, G.A. Zickler, F.D. FischerAbstractInteractions of impurity interstitial atoms with dislocations may play an important role in strengthening of structural materials as well as in other phenomena like hydrogen embrittlement. Impurity interstitial atoms occupy octahedral (typical for carbon) or tetrahedral (typical for hydrogen) sites in bcc metals, both showing solely tetragonal symmetry of three types distinguished by orientation with respect to the main crystallographic (1, 2, 3) directi...
