Considering lightweight material application status at present, three material substitution plans are determined.
Determine the above three materials substitution schemes and origin hood as possible options, namely scheme sets A={ST14;ST14 for inner and aluminum alloy for outer; aluminum alloy; magnesium alloy}.
Define material scheme mi (i = 1,2,3,4) as design variable.
The performance of four material schemes is shown in Tab. 3.

Experimental procedure Hot-rolled magnesium alloy AZ31 sheet was chosen as the initial material.
The material was annealed at 500℃ for 3h in order to obtain mean equiaxed grains (～25µm).

Information about safety valve including the material of the facture spring can’t be provided.
Therefore the spring material didn’t meet the requirement for spring steel.
Finally, improper material selection contributes to the failure.
Unsuitable material was also a reason for the failure. 4.

Transparent conductive oxides are materials combining great transparency with high conductivity.
There is a class of semiconductor materials with this set of specific properties (transparency and high conductivity at the same time), these materials are called Transparent Conductive Materials (TCM), some of these materials are oxides, and among them, ITO (In2O3: Sn) is no longer used in a wide range of optoelectronic applications and in particular in photovoltaics despite its excellent conductivity and transparency.
A first Figure of Merit (FoM) [10] was used to compare between TCO materials.
