Abstract In this study, four different combinations of aluminium metal matrix composites (AMCs) were produced using a computerized stir casting process. The feasibility car Scrap Aluminium Engine Head (SAEH) as material, Fresh Alumina Catalyst (FAC) and Spent (SAC) from petrochemical industries reinforcement material investigated. physical mechanical properties the cast samples tested through d...

This topic prepared a composite nano-silver–tin slurry. According to the boiling point of dispersant, 300 °C is determined as sintering temperature. As amount tin added increases, shear strength Ag–Sn slurry gradually increases. When 1/20, reaches maximum 50 MPa. The increase in due strengthening second phase. exceeds drops sharply, mainly overgrowth Ag3Sn, product reaction silver and tin. poro...

The main objective of this paper is to develop methods for assessing the deterioration wooden panels iconic heritage objects and effectiveness consolidation treatments, that are easy apply field wood restoration. During research, four evaluation were identified, respectively: density method, excessive porosity Brinell hardness Mark method. Each method was exemplified on five (icons), when neede...

A comparative analysis of the mineralization wood with a solution an organic mineral complex in various modes is carried out: spontaneous (by immersion container solution) and forced (during autoclave treatment under excessive pressure using inert gas) modes. This will reveal optimal parameters mineralization, which, turn, help to solve problem increasing durability reliability materials intend...

Gray cast iron has a drawback, that is very low ductility value so when subjected to tensile forces fracture plane will form because graphite resembling mica brittle. To get with high strength, the of Sc (eutectic degrees) must be smaller and also by adding little calcium silicon or ferrous molten just before pouring, prevent formation white iron, thus produced finely dispensed evenly on pearli...

Tannin polyphenols are produced by plants to protect themselves against natural decay. It is expected that impregnating low-durable timber with tannin extracts of more durable species such as quebracho (Schinopsis balansae) will enhance the durability specimens. This biomimetic approach combined in situ polymerization quebracho–hexamine formulations can be a valid alternative synthetic wood pre...
