    Abstract: The microstructure and mechanical behaviour of Ni-B binary alloys have been enhanced in this study by varied titanium additions. The alloys investigated were chosen from the nickel-rich region of the Ni-B-Ti system. The microstructure of the alloys was examined using Optical Microscope (OM) and Scanning Electron Microscope (SEM) equipped with Energ... Show More

    Abstract: Asphalt, sometimes known as Bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It is mainly found in natural deposits or may be a refined product. The primary use (70%) of asphalt/bitumen is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. The ... Show More

    Abstract: The Heusler alloy is with a ordered structure, in which the atoms are in specific location, and the alloy usually shows special character. The Co Mn Ni based Heusler alloys are all studied in many literature, but there is little study of the Cr based Heusler alloys. In order to find new Heusler alloys, Cr2AgAl and Cr2ZnAl are studied by first princ... Show More

    Abstract: A detailed knowledge of structure and energy of surface contributes to the understanding of many surface phenomena. In this work, the surface energies of 48 surfaces for diamond cubic crystals, including diamond (C), silicon (Si), germanium (Ge), and tin (Sn), have been studied by using the empirical electron surface models (EESM), extended from em...
