Due to the superior mechanical and thermal properties of SiCp/Al composites, their poor machinability has been the main deterrent to their substitution for metal parts.
In the past, the machinability of SiCp/Al composites has been studied by various researchers, and it is found that the morphology, distribution and volume fraction of the reinforcement phase, as well as the matrix properties, are all factors that affect the cutting process [4-6].
Results and discussion The measurement of cutting force components is highly essential to analyze more effectively the machinability properties of SiCp/Al composites.
On the other hand, the speed range in this study is not large enough to cause the machining properties varied remarkably.
The tool rake angle is another factor that affects the cutting force, so the cutting forces at different tool rake angles were also measured in the experiments.

Knowledge about the dynamic properties of concrete is vital to the design and safety evaluation of large-scale concrete structures subjected to seismic excitation.
There are many factors affecting the dynamic properties of concrete such as moisture content and temperature.
Introduction A lot of research works concerning the dynamic properties of concrete have been performed over the past several decades.
However, minority of these experimental works are carried out regarding environmental factors such as moisture content and temperature.
But studies on the dynamic properties of concrete under such low temperature have not been reported in the current documents.

Ti is one of the potential elements that can be expected to increase the mechanical properties of NiAl at elevated temperatures [10].
The objective of this work was to investigate the effect of Ti addition on the structure and mechanical properties of the formed phase prepared by Ni-Al-Ti system using combustion synthesis.
