Strengthening creep

At half of the solidus temperature on the absolute temperature scale (i.e., 1850°C for tungsten), solid-solution alloys lose much of their strength, and dispersion-strengthened or precipitation-hardened alloys are significantly stronger and creep resistant. This is caused by the interaction between the dispersoids and dislocations, as well as subgrains and grain boundaries. [Pg.259]

Thus, the aim of the present paper is not to review the bulk of the results published to date relating to the creep response of various magnesium-based composites. Instead of such an approach this paper provides a comprehensive report on the extensive experimental results obtained by authors in an investigation of the high temperature creep behavior of the two magnesium alloys, AZ 91 and QE 22, and their discontinuous composites. The objective of the present research is a further attempt to clarify the direct and indirect strengthening effects of short-fiber and particulate reinforcements in creep of magnesium-matrix composites. [Pg.204]

The creep resistance of discontinuous magnesium composites can be significantly improved by comparison with the unreinforced matrix alloys in two separate ways. Direct strengthening of the composites arises mainly from effective load transfer provided that no debonding of the... [Pg.213]
