To develop in-depth understanding of metallurgical phenomena for completeness, mechanical heterogeneity is kinetically and thermodynamically explained by thorough microstructure characterization engineering materials, e.g. polycrystalline nickel-based superalloy, alleviation weldability-related problems during laser-induced keyhole fabrication. Because nonequilibrium solidification behavior ins...
Microstructural examination can provide a rich tapestry of information about the processing and application history of a metal component. For this reason, microstructural characterization is a fundamental tool for failure analysis of these components. To reduce costs and accommodate demands for smaller packaging, many applications currently use metallic components where the critical dimensions ...
Urban segregation has been a problem of many cities of the world. Many researchers have interested in the urban segregation issues. Urban segregation has strongly concentrated poverty and created underclass. Different types of urban segregation exist, including income and racial or ethnical segregation, and depending on the contextual mechanisms within a city. To understand and plan a better co...
Reticulated mesh samples of Co-29Cr-6Mo alloy and Ni-21Cr-9Mo-4Nb alloy (625) and stochastic foam samples of Co-29Cr-6Mo alloy fabricated by electron beam melting were characterized by optical metallography, and the dynamic stiffness (Young's modulus) was measured by resonant frequency analysis. The relative stiffness (E/Es) versus relative density (ρ/ρs) plotted on a log-log basis resulted in ...
