Introduction Tailor welded blanks (TWBs) are composed of more than two materials with similar or different strengths or thicknesses joined together to form a single part before the forming operation [1].
The profile and size of test specimens depends on the dimensions of metal materials, the efficacious length of the specimen should be larger than original gauge length.
To study the mechanical properties difference between base metal and TWBs, the test plan had designed two base materials tensile test and the TWBs with three different weld line locations ones.

Ceramic oxides are suitable materials for EBCs because in general are more corrosion resistant than other ceramics.
There are several factors that must be considered in selecting coating materials including the high thermal stability, the high corrosion resistance, the minimum difference between coefficients of thermal expansion (CTE) of involved materials and the chemical compatibility between contiguous materials [[] K.N.
