For T6 materials, a higher quench rate tends to improve EXCO and IGC resistance and to delay SCC failure.
Two sorts of initiation are observed depending on the IGC sensitivity of the alloy: intergranular corrosion for IGC sensitive materials or intragranular corrosion for IGC insensitive materials.
This study suggests the following mechanism for exfoliation corrosion with two sorts of initiation depending on the IGC sensitivity of the alloy: intergranular corrosion for IGC sensitive materials or intragranular corrosion for IGC insensitive materials.

Mine workplace risk prevention management Mining workplaces are evaluated by using LEC, evaluation results indicate that the place is highly dangerous and requires immediate rectification.Considering that enhance security management can reduce system reality in real danger, risk analysis methods are appropriate for the job conditions.Namely increases a parameter in the original mathematical model foundation M,Called safety management factor,Mainly related to four aspects of security management：M：Job personnel management, M:Equipment management, M：Materials management, M： Working environment management.Therefore, security management coefficient can be expressed as: .By strengthening safety management, improved LEC law can be expressed as a formula: Four management coefficient of the safety control coefficient sees the Table 6~Table 9.

As people’s living standard’s improving, it becomes common to see obese children, so our kids can play with the swing machine and exercise their bodies to lose weight at the same time. 3 Rapid prototyping manufacturing The first thing we do is materials selecting and production process outputting.
It saves materials and extends the using period as well, which includes the entertainment.
Today’s society promotes energy efficiency, such a material-saving and durable cycle will be the trend.

For the building frame insulation, wool insulation material (Possibility of local industrial development) and EPS panel (Expanded Poly-Styrene) which is popular in China are used, and for the openings, the multi-layer glass is installed.
In addition, the difference in thermal conductivity of the insulating material, the indoor temperature is higher using EPS panel than the wool insulation material.
Residents provide biomass resources which become raw material for methane gas, and the heat is provided by the local methane gas boiler.
Compared to acquisition of raw material for biomass are relatively stable, solar power relies on weather, so it requires the auxiliary heat source for winter heating supply. 5.
