To provide insight into the relationships between precipitation phenomena, grain size and mechanical behavior in a complex precipitation-strengthened alloy system, Al 7075 alloy, a commonly used aluminum alloy, was selected as a model system in the present study. Ultrafine-grained (UFG) bulk materials were fabricated through cryomilling, degassing, hot

Strengthening Mechanisms in Sapphire
1975Strengthening of sapphire by work hardening, solid solution hardening and precipitation hardening is described. Examination of the dislocation structures in pure sapphire deformed by basal glide has led to the development of a semi-quantitative work hardening model; edge dipoles, formed by trapping of dislocations on parallel slip planes, are the ...

Abstract This chapter discusses the metallurgical changes that occur and the improvements that can be achieved in superalloys through solid-solution hardening, precipitation hardening, and dispersion strengthening. It also explains how further improvements can be achieved through the control of grain structure, as in columnar-grained ...

Strengthening mechanism of bonded alumina crowns
The Journal of Prosthetic Dentistry, 1981The results of this study suggest that the strengthening of aluminous porcelain with Sn-plated Pt is an effect of (1) a chemical interaction involving diffusion and dissolution of Sn-oxide in the glass phase of the porcelain and (2) a better wetting of te Sn-plated substrate by the porcelain. This conclusion supports and confirms the earlier hypothesis
