Alpha-phase titanium alloys areless ductile and have less strength than the beta-phasealloys, but have higher corrosion resistance anddeformability. Carbon is considered to be an impurity,commonly introduced during the manufacturingprocess, of commercially pure (CP) titanium grades.
作为铜矿优先浮选、硫精矿浮选过程中有危害性的硫化锌含量一般会限制在一定的范围以内。随着EDX荧光仪器的分辨率和灵敏度的大幅提高,以及快速无损分析和操作简单的优势,加之EDX荧光分析对样品要求不高(甚至可以直接测试矿浆),EDX荧光光谱仪越来越多地用于地矿浮选工艺中的元素分析。使用岛津EDX-LE Plus 荧光光谱仪可以直接对矿浆样品进行快速无损分析,无需烘干或压片,可以随时取样分析,操作简单而又快捷。
Ferroalloys are alloys of iron that contain a high level of one or more other primary elements. The principle ferroalloys consist of silicon, manganese, and chromium that are used as vehicles to introduce the alloying element into the molten metal when making steel or cast iron. For example, silicon is used to deoxidize steel and as an alloying element in cast iron. Manganese is used as an alloying element and mitigates the harmful effects of sulfur in cast iron and steel. Chromium increases corrosion resistance in stainless steels. Since carbon is the most important alloying constituent in steel and cast iron production, and sulfur is a harmful contaminant that negatively affects the mechanical properties of steel and cast iron, the determination of carbon and sulfur levels in the ferroalloy feed stock is a critical quality control parameter.
