| Abstract: |
| This thesis discusses how to determine the density and the method of open porosity of metallurgical powder material, then pointing out that any systematic and accidental errors should be avoid when precisely measuring the object of density by the immersed method in water. No waterproof membrane is used in the process of the experiment, allowing water to fully immerse porous materials。This can help fix density calculation formula by the immersed method in water precisely. It has been proved that this method is easy to operate, of high accuracy, and can be used in metallurgical powder material field. |
