Interface reaction [B. sub. 4]C-The 2519Al system was analyzed by scanning electron microscope (SEM)Electron probe X-Raymicroanalysis (EPMA)and X-Ray diffraction (XRD). Typical bending strength and hardness of penetration [B. sub. 4]C-2519Al composite material is three-point-Bending test and Rockwell hardness tester. The study found that the molten 2519Al alloy [B. sub. 4]C is sensitive to temperature and contact time.
For example, Costco Kirkland\'s signature received nearly $40 billion last year, an increase of 11% over 2017. Last year, Kirkland sold more than Campbell Soup, Kellogg and Hershey combined. Retail brands challenge these consumer goods giants that spend billions of dollars marketing their products.
