Here, the microstructure and mechanical properties are investigated for the designed Mg-4Gd-0.5Zr-xZn (x = 0, 0.2, 0.5, 1.0 and 1.5 wt%) alloys with special emphasis on the effect of Zn. The results show that the designed Mg-4Gd-0.5Zr-xZn alloys exhibit the exceptional ductility. Among them, the...

Microstructure, texture and mechanical properties of extruded Mg- x Gd sheets (x =1.0, 1.5, 2.0 and 2.5 wt%) were discussed, and microstructural evolution of an Mg-1.0Gd alloy during extrusion were investigated. The extrudedMg- x Gd sheets presented a fully recrystallized microstructure. The...

While Magnesium (Mg) matrix composites have been intensively investigated as the promising light structural materials, the relatively low ductile nature limited their wide-scale applications. Herein, we report that AZ91 Mg matrix composites reinforced by Ti-6-Al-4V (TC4) particles were prepared...

For basal textured magnesium alloy subjecting to in-plane compression, the deformation is complicated since twinning, dislocation slipping and their intersecting are involved. In this work, a high-resolution digital image correlation (HR-DIC) technique combined with electron backscatter...

We investigate the value-growth premium puzzle by merging insights from urban economics and finance that relate firm location to its stock performance. The value-growth premium in locations with high historical house price appreciation is 3.6% larger per year than the premium in areas that...

This study provides evidence of informational efficiency in the housing market, where prices fully incorporate available information. We use Amazon's progressive disclosure of its new headquarters locations in Virginia and New York to distinguish changes in the public's knowledge. Using a...

Some U.S. local governments are leveraging public procurement to meet their sustainability goals. However, does the simultaneous pursuit of multiple sustainability objectives potentially slow down the speed of procurement processes? We suggest that the simultaneous pursuit of multiple...

The South Korean Ministry of Environment, Korea Environmental Industry and Technology Institute, Ministry of Economy and Finance, and Public Procurement Service are working collaboratively to promote green purchasing policies across all levels of South Korean government. A primary reason for...

In 2019, the Spanish government published a Presidential Order approving the General State Administration’s Green Public Procurement Plan. This plan covers all public administrations including the General State Administration, its autonomous bodies, and social security management entities. Its...

Italy was the first European country to create a full mandatory plan known as the National Action Plan on Green Public Procurement. This plan established a framework through which green purchasing polices can diffuse throughout Italian municipalities. A primary reason for this action is that...
