The mechanical properties of new material may have capability to be further process as thermoplastic elastomer.
The mechanical properties were determined at 100 and 300 % elongation.
The comparison on the mechanical properties of conventional floor mat and starch TPE at 100 and 300 % elongation is shown in Table 2.
There were various kinds of environment factors that cause the increment of VOCs, such as temperature, humidity and airflow velocity [22].Comparison on the VOCs released Starch TPE and floor mate was done.
In this study, it was found that temperature was the main factor that affected the concentration of VOCs.

The main factors affecting the peak values of the interfacial stress was also investigated entirely.
The effect depends on two factors such as the distance of plate end from the support and plate thickness.
But it affect the save use of the reinforced structure, therefore, the analysis of the bonding shear stress at the end of Strengthening plate has attracted much attention[1].

Effect of Cutting Speed During Turning of Low Carbon Steel on Mechanical Properties and Surface Roughness ZAKARIA Boumerzoug1,a, FETHI Remli1 and FABIENNE Delaunois1 1Mechanical Engineering Department, Biskra University, B.P. 145, Biskra, Algeria 2 Metallurgy Department, University of Mons, Belgium 3List all distinct addresses in the same way azboumerzoug@yahoo.fr Keywords: turning; cutting speed; surface roughness ; low carbon steel.
We have found that the cutting speed affects the surface layer of a workpiece, induces hardening of the surface, and increases the surface roughness.
Introduction Turning is one of the major manufacturing processes used to produce mechanical parts.
It was found that the surface finish in turning is influenced by several factors such as feed, work material characteristics, workpiece hardness, coolants, cutting speed, depth of cut, tool nose radius and tool cutting edge angles [9-10].
From this investigation, width of surface layer affected by machining was determined.

The microstructure in the simulated coarse-grained heat-affected zone was predominantly bainite.
Welding thermal cycle simulation is often used to simulate the welding thermal cycle of coarse-grained heat affected zone (CGHAZ), and thus to analyze the microstructures and mechanical properties, which can provide some technical reference for real welding parameters.

Pcm is an important factor to influence the weldability of high strength steels, which is significantly affected by the carbon content.
(2) When the Zr-Ti microalloyed pipeline X120 steel plates were welded with the heat input of 21 kJ/cm, the heat-affected zone of the steel plates had high yield strength (895 MPa) and low temperature (-30°C) impact toughness (183 J, 204 J and 208 J in the fusion line, coarse-grained heat-affected zone and fine-grained heat-affected zone, respectively).

Biomaterial components (PMMA/HA/Sericin) are composite biomaterial that has complemented each other, which HA is able to improve the mechanical properties, biocompatible and osteoconductivity.
Hydroxyapatite (HA) has osteoconductive properties and osseointegration properties [2-4], but pure HA powder was difficult to be shaped due to brittleness characteristic [8].
In fact, the addition of hydroxyapatite in a mixture of PMMA can improve the mechanical properties, biocompatibility, and osteoconductivity [5].
Taguchi is able to analyze the significant influence of many factors (variables) but without considering the interaction between factors, whereas a Factorial design method is able to determine the effect of the significant parameters of the response as well as the influence of interaction between factors [9].
