Robust Line Hardening Strategies for Improving the Resilience of Distribution Systems With Variable Renewable Resources

IEEE Transactions on Sustainable Energy, 2019
Line hardening refers to strengthening certain distribution lines that will not be subject to outages during extreme conditions. Line hardening provides a resilient solution in the case of major faults in a radial or meshed distribution system.

Effect of natural ageing or pre-ageing on the evolution of precipitate structure and strength during age hardening of Al–Mg–Si alloy AA 6016

Materials Science & Engineering: A, 2019
In this study we demonstrate the complementarity of transmission electron microscopy (TEM) and atom probe tomography (APT) in studying the early stages of phase decomposition in the age-hardening Al–Mg–Si alloy AA 6016.

Interface-induced strain hardening of graphene nanosheet/aluminum composites

Carbon, 2019
Interface effect was a key mechanism for the deformation of metal matrix composites, which has not been well understood yet in those reinforced with nanoreinforcements. In this study, we prepared graphene nanosheet reinforced aluminum (GNS/Al) composites

Strain hardening of as-extruded Mg-xZn (x = 1, 2, 3 and 4 wt%) alloys

Journal of Materials Science & Technology, 2019
The influence of Zn on the strain hardening of as-extruded Mg-xZn (x = 1, 2, 3 and 4 wt%) magnesium alloys was investigated using uniaxial tensile tests at 10 s at room temperature.

Surface hardening of steels by plasma hardening

Metal Science and Heat Treatment, 1983
1. Plasma hardening of steels provides hardened layers which in hardness, thickness, and wear resistance meet the requirements for hardened surfaces of many parts of various types of machines. 2. From the results of production and testing under service conditions of lots of hydraulic motor stators and troughs of conveyers it was ...

Surface hardening of precipitation-hardening nonmagnetic steels

Metal Science and Heat Treatment, 1973
1. Precipitation-hardening nonmagnetic steels of the Fe−Mn−Ni system can be surface hardened by nitriding and also by work hardening of the surface. Surface layers with an elevated hardness to a depth of 0.3 mm can be obtained by nitriding of high-strength nonmagnetic steel 40G14N9Kh3YuF2. The results of comparative wear resistance tests showed that

Annealing-induced abnormal hardening in a cold rolled CrMnFeCoNi high entropy alloy

Scripta Materialia, 2019
A CrMnFeCoNi equiatomic high entropy alloy (HEA) with a single solid solution was cold rolled, followed by annealing treatment. Annealing-induced abnormal hardening was observed for cold rolled alloy after annealing treatment at 773 K.

Hardenability

1996
Abstract The crux of this chapter is to develop a method to quantitatively define hardenability. The chapter includes the empirical methods to estimate the hardenability knowing the chemical composition, describes prior austenite grain size, and examines their utility.
