The material property of this alloy and the low cost is one of the advantages it poses on other alloy element in the current market [1].
One of the most influential directives was by the EU; the waste Electrical and Electronic Equipment directive (WEEE) have levied constraint on lethal materials which includes Pb in electrical and electronic equipment after 1st of July 2006.

Abstract.Strain measurement in electromagnetic rail launching processes is of significant importance to studies on rail life, wrap material selection, and initial armature disturbance.
Rail strain also influences the rail life and wrap material life, so it is difficult to ensure the consistency of muzzle velocity under the same muzzle voltage environment.

Introduction Inorganic polymers are cementitious materials using industrial by-products as the main raw material, excited by properly configured activator solution.
A research by En Wang from Beijing University of Science and Technology [2] indicated that the different raw materials (such as slag, and fly ash and the kaolin) and different region perform differently under alkali-activator.
Reference to the experience of ordinary cement and concrete, adding appropriate admixture and mixed materials to inorganic polymer material is a good solution.

The material of cast steel is assumed to be perfectly elastic-plastic, the modulus of elasticity is 2.06×105N/㎜2 and yield strength is 230 N/㎜2.
The effect of material strength on bearing capacity Bearing capacity of cast steel spherical joint is tightly related to strength f.
When all material of the sphere which is located at the outer fillet behave plastically, obvious plastic deformations occur and the joint is damaged.
