Quantification of Precipitation Hardening and Evolution of Precipitates
Quantification of precipitation hardening is a challenging subject as it demands combined knowledge of precipitation strengthening mechanism and precipitate growth/coarsening kinetics. Having not seen many attempts on developing new theories in recent years, the authors are aware of the fact that many existing concepts and developed theories are sometimes even neglected or misused. This article...
متن کاملSome factors affecting fibrinogen precipitation by ristocetin: ultrastructure of precipitates.
Fibrinogen in aqueous solution is precipitated by the antibiotic ristocetin. This reaction is inhibited by albumin and facilitated by low temperature. Resolubilized fibrinogen clots in the presence of thrombin. Ristocetin-precipitated fibrinogen takes the form of fibrils or clumps, composed of irregularly spaced, structure-less particles. The addition of ristocetin to washed platelets suspended...
متن کاملPrecipitates and intermetallic phases in precipitation hardening Al–Cu–Mg–(Li) based alloys
The present study contains a critical review of work on the formation of precipitates and intermetallic phases in dilute precipitation hardening Al–Cu–Mg based alloys with and without Li additions. Although many suggestions for the existence of pre-precipitates in Al–Cu–Mg alloys with a Cu/Mg atomic ratio close to 1 have been made, a critical review reveals that evidence exists for only two tru...
متن کاملDevelopment of a Nanoscale Precipitation-Strengthened Creep-Resistant Aluminum Alloy Containing Trialuminide Precipitates
Development of a Nanoscale Precipitation-Strengthened Creep-Resistant Aluminum Alloy Containing Trialuminide Precipitates Keith Edward Knipling This research is toward developing a castable andheat-treatable precipitation-strengthened aluminum alloy exhibiting coarseningand creep resistance at temperatures exceeding 400°C. Criteria for selecting alloying elements capable of producing such an al...
متن کاملInfluence of AgCl precipitates on the precipitation titration of sodium chloride by constant-current coulometry.
The precipitation titration of sodium chloride with electrogenerated silver ion was studied. The production of a precipitate of silver chloride had a significant effect on the titration results because the precipitate involved unreacted chloride or unreacted silver ion. The accuracy of the method was investigated by changing the introduction time of a sodium chloride solution to the coulometric...
