Abstract Precipitation hardening is used extensively to strengthen aluminum alloys, magnesium alloys, nickel-base superalloys, beryllium-copper alloys, and precipitation-hardening stainless steels. This chapter discusses two types of particle strengthening: precipitation hardening, which takes place during heat treatment; and true ...

Recent Advances in Solids/Structures and Application of Metallic Materials, 1997
Abstract A model/method was developed for predicting the precipitation hardening response of particle strengthened alloys hardened by ordered precipitates based on the microstructure, composition, and heat treatment, and utilizing a minimum number of experimental tests.

Precipitation hardening in metals
Materials Science and Technology, 1999AbstractPrecipitation hardening has long been used to increase the strength of commercial alloys, such as quenched and tempered steels and the duralumin type aluminium alloys. The theoretical treatments of precipitation hardening are briefly considered.

Precipitation Hardening in Ceramics
1974The science of “heat treatment”, i.e., the control of microstructure by use of subsolidus reactions involving changes of composition or symmetry or both, and attendant improvement of properties, has received less attention in ceramic systems than in metallic systems.

Precipitation hardening of HSLA steels
Steel Research, 1998A process model to describe the strength contribution from precipitation hardening during coiling after hot rolling has been developed for V and Nb HSLA steels. Experimental measurements of ageing behaviour on the V steel were conducted on coil material which was received in an underaged condition.

We said in the introduction that metallic alloys have mechanical properties which are far more interesting than those of pure metals. By means of alloys we are enabled to manufacture machine parts which are lighter, or more resistant for the same weight, than those made from pure metals.

Precipitation hardening of aluminum alloys
Metallurgical Transactions A, 1975The author’s charge was to discuss recent trends in research and development on precipitation hardened aluminum alloys and to indicate where research is needed. This will be done for three areas: fatigue, properties of grain boundaries and interfaces, and stability of precipitates at elevated temperatures. Present strong precipitation hardened aluminum

A significant precipitation-hardening response has been observed in rapidly quenched Al6Ti1.5Ni (wt.%) alloy aged isothermally in the temperature range 300–500°C, and the underlying precipitate microstructures characterised using transmission electron microscopy (TEM).

Hundred years of precipitation hardening
Journal of Light Metals, 2001Abstract About 100 years ago, precipitation hardening was discovered and the first structural aluminum alloys with considerable strength were developed. Our present understanding of the phenomenon in based on the application of dislocation theory as well as reaction kinetics, especially the role of metastable phases and lattice defects in nucleation ...
