Thermal properties of both materials were measured using DSC and heat absorption were tested under real solar irradiation.
These thermal energies will be stored and keep by PCM materials to gives better performance and can be utilized in generating continuous electricity even the light source is absent.

These alloys have
been classified as difficult-to-machine materials.
Titanium and titanium alloys have low thermal conductivity and high chemical reactivity with many cutting tool materials.
The difficulty of this method is concerned with the necessity for an accurate calibration of the tool and workpiece materials as a thermocouple pair [11].

Lots of damage specimens of water pipelines, made of different materials, were gathered in different intensities.
(b) The effect of pipeline material to the vulnerability during an earthquake is obviously.
The seismic performance of the in-service water supply pipelines with different materials is further understood and the following conclusions can be made: a) The vulnerability of pipelines with different materials differ greatly.The seismic performance of PPR pipes and ductile cast iron pipes is quite well during the earthquake.
