AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...
High specific strength of the material is critical for many structural applications in automotive and aerospace design. Among many other approaches for strengthening the materials, development of superfine and nano grained microstructure is becoming popular. Different techniques for producing ultra-fine-grained (UFG) materials have been introduced especially in the last decade. The advantages o...
Injection molding is one of the most common processes which are used for manufacturing different plastic parts. This method includes 3 continuous steps: filling of the mold, cooling and driving the part out. A wide range of plastic and Non-Plastic materials can be used as raw material in this process. One of the most important advantages of this way of production is that it is very economic. In...
There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete fil...
were analyzed for percentages of African-Americans, Hispanics, and Asians in U.S. surgical residency programs (1995 – 2014). Percentages were compared between integrated and independent plastic surgery residents (2008 – 2014) and the composite was compared with other surgical disciplines. Percentages of minority groups were compared between plastic surgery residents, U.S. medical school graduat...
