There exists a wide variety for critical value reporting in hematology in China. Laboratories should establish a policy of critical value reporting suited for their own situations and consult with clinicians to set critical value lists. Critical values are generally reported in a timely manner in China, but some measures should be taken to further improve the timeliness of critical value reporting.
In order to refine and homogenise microstructure and to improve mechanical properties of the magnesium alloys for biomedical application, the Mg-2.0Nd-0.1Zn-0.4Zr (wt-%, NZ20K) alloy with low amount of alloying elements was processed by double extrusion and aging processes (DEAP). Compared to the NZ20K alloy after once extrusion and aging processes (OEAP), the microstructure becomes finer and more homogeneous, and the elongation is raised up ∼121% by DEAP. Moreover, the yield strength and ultimate tensile strength are improved ∼27 and ∼16% respectively. Additionally, the corrosion rate of the NZ20K alloy by the DEAP is a little slower than that of the OEAP. It can be concluded that the mechanical properties, as well as the corrosion resistance of the NZ20K alloy, are able to be enhanced by the double extrusion and aging processes.
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.
