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...
متن کاملPrecipitation Hardening of Metal Alloys
Precipitation hardening, or age hardening, provides one of the most widely used mechanisms for the strengthening of metal alloys. The fundamental understanding and basis for this technique was established in early work at the U. S. Bureau of Standards on an alloy known as Duralumin [1,2]. Duralumin is an aluminum alloy containing copper and magnesium with small amounts of iron and silicon. In a...
متن کاملDetermination of Critical Cooling Rate for Hardening Aluminum Alloys using HyperDSC
When an aluminum alloy is solution annealed and afterwards cooled too slowly, an exothermal precipitation reaction occurs. With increasing cooling rate, the precipitation heat decreases. Since the precipitation reaction is relatively fast, a fast cooling rate on the differential scanning calorimeter (DSC) is essential to obtain the critical cooling rate which is the minimum cooling rate at whic...
متن کاملAluminum and Aluminum Alloys Casting Problems
Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...
