AGE HARDENING IN HYDRONALIUM SHEETS

High-strength age hardening copper–titanium alloys: redivivus

In this review the decomposition of supersaturated Cu–Ti solid solutions and subsequent microstructural evolution are discussed in terms of modern views of precipitation from solid solution. This update is motivated by an anticipated emergence of these alloys as technologically significant high-strength, high-conductivity, precipitation hardened alloys over the next decade replacing conventiona...

TLS hardening

This document presents TLS and how to make it secure enough as of 2014 Spring. Of course all the information given here will rot with time. Protocols known as secure will be cracked and will be replaced with better versions. Fortunately we will see that there are ways to assess the current security of your setup, but this explains why you may have to read further from this document to get the u...

Enhanced Age Hardening in an Al-Mg-Si Alloy Using High-Speed Compression

The age hardening of an Al-Mg-Si alloy was enhanced by the effect of high-speed (105 s11) compression prior to aging. This enhancement of the age hardening is brought about by the formation of vacancy clusters during high-speed compression. High resolution transmission electron microscopy reveals that these vacancy clusters form stacking fault tetrahedra. Following peak aging, vacancy clusters ...

Nanostructuring and Age Hardening in TiSCN, ZrAlN, and TiAlN Thin Films

Isothermal age-hardening behaviour in commercial dental gold alloys containing palladium.

The isothermal age-hardening behaviour in the commercial dental gold alloys containing palladium was studied by means of resistometric, hardness, X-ray and electron microscopy. Drastic overageing occurred following prolonged ageing. The mechanism of the overageing was interpreted as a loss of coherency at the interfaces of the adjacent lamellae which consists of the equilibrium AuCu I ordered p...
