1. Water in microporosity or other small pores.

2. In addition, the less and smaller microporosity in AG40A zinc alloy die castings with vacuum assist than those without vacuum assist via SEM and OM observations.

3. Microporosity of the Surface of Gold Plated Contacts which indicates the protection performance of plating layers to matrix is an important index for quality of plating surface features.

4. However, the size and amount of microporosity increase with the recycle material proportion, and the microporosity in 100% recycled alloy is much more than that in the virgin alloy.

5. Microporosity has no apparent change and extent of elements segregation slightly decreases.

6. Formation mechanics of microporosity is coincident with the model of gas forming and the law of solute reallocation; therefore it can verify microporosity forming mechanism of hydrogen evolution.

7. Formation mechanism of microporosity is the results of interaction between thermodynamics and solidification mechanism.

8. The results show that the microporosity morphologies transform from fine porosity to microporosity with the increase of the samples thickness of cast magnesium alloy.

9. The results show that there was obvious microporosity at the positions indicated by fluorescence, and clear grinding traces and some local microcracks were found at the dovetails.

10. Result is microporosity,[/microporosity.html] second - phase precipitation and inclusions of intermetallic or nonmetallic compounds.

11. The microporosity of the wall structure was evaluated by the nitrogen adsorption determination.

12. The microporosity morphology and formation mechanism of cast magnesium alloy was investigated with software for analysis percentage of microporosity and field scanning electron microscopy.

13. The effects of foundry variables and refiners on dendrite structures, micro segregation, inclusion and microporosity of cast superalloy K4169 have been studied.

14. This, in turn, creates a finished die cast product with extremely low levels of microporosity defects.

15. The effect of some components, such as initiator AIBN, methacrylate and unsaturated polyester, of impregnation microporosity sealants on their heat resistance were studied.

16. By means of using a special aerated technology of micropore-making and stabilizing with compressed air to get high microporosity , and fine, uniform-d...

17. It is consists of cappilly pipe tube sealed at the bottom, with amount of microporosity on pipe wall and connected to the sample capillary of the ICP-AES nebulizer.

18. The alloys of the present invention also have a modified eutectic silicon and modified iron morphology, when iron is present, resulting in low microporosity and high impact properties.

19. Advanced tests like corrosion resistance to molten aluminium, thermomechanical properties, thermal conductivity and microporosity are discussed in respect of application areas for Bonite.
