Tensile and fatigue behavior of AZ91D magnesium alloy
Recently magnesium alloys, owing to their low density and excellent specific strength have been attractive to designers as an advanced material for coping with energy conservation and environmental pollution regulations. Much of the recent developments of magnesium alloys and processes have been driven by the requirements of the aerospace industry, although some successful ones have found appli...
متن کاملTowards Superplastic Forming of Az31 Magnesium Alloy with Controlled Microstructure
A recent study on post-superplastic forming properties has shown that heating time prior to testing has a major effect on the post-forming properties of superplastically-formed AZ31 Magnesium alloy sheets. To this point, there has been very little examination into the effects of pre-heating or annealing on superplastic forming. In this work, these effects are examined using AZ31 Mg alloy sample...
متن کاملCharacteristics of Cavitation in a Superplastic Magnesium Az31 Alloy Processed by Equal- Channel Angular Pressing
Experiments were conducted on a magnesium AZ31 alloy to evaluate the role of cavitation in high temperature superplasticity. Samples were processed by equal-channel angular pressing (ECAP) and then pulled to failure in tension at a temperature of 623K. Similar tests were also conducted on the as-received alloy. The results show the development of significant internal cavitation in this alloy wh...
متن کاملMicrostructure and Aging Behavior of Nonflammable AZ91D Mg Alloy
Phase equilibria of AZ91D Mg alloys for nonflammable use, containing Ca and Y, were carried out by using FactSage® and FTLite database, which revealed that solid solution treatment could be performed at temperatures from 400 to 450C. Solid solution treatment of AZ91D Mg alloy without Ca and Y was successfully conducted at 420C and supersaturated microstructure with all beta phase resolved into ...
متن کاملAchieving superplastic properties in a ZK10 magnesium alloy processed by equal-channel angular pressing
Equal-channel angular pressing provides an opportunity for refining the grain structure and introducing superplastic properties in magnesium alloys. This report describes the use of this processing technique with a ZK10 (Mg–1.0 wt.% Zn–0.26 wt.% Zr) alloy. The grain structure was successfully refined from ∼12.9 to ∼5.2 m after 4 passes and superplastic elongations were observed when testing at ...
