Nanostructured Al-Zn-Mg-Cu alloy and boron carbide/Al-Zn-Mg-Cu composite powders are fabricated through cryomilling. η'-MgZn 2 precipitation in each material is characterized through differential scanning calorimetry. The activation energy of η' precipitation is derived through Kissinger analysis. The addition of boron carbide to nanostructured Al-Zn-Mg-Cu powder increases the onset and peak temperatures of η' precipitation, but do not significantly affect the activation energy. Further analysis of uncertainties in measurement indicates that weighted least squares linear regression is a more reliable method that supplements the use of differential scanning calorimetry as a method for rapid characterization of precipitation in materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
