| Sumario: | Magnesium alloys find their application in aviation technology for manufacturing of structural elements in uninhabited compartments and outside areas with increased fire hazard. At the stage of development of magnesium alloys with low fire hazard, it is advisable to perform comparative tests on relatively small samples so that all test equipment can be located in a laboratory. A method has been developed for conducting flammability tests when exposed to a flame with a temperature of 1,100 ° C for samples of magnesium alloys of small sizes. Comparative tests of two magnesium alloys - the standard ML5 and the new experimental one with increased fire safety - have been carried out. Significant differences have been established in the flammability and extinguishing ability of various grades of magnesium alloys - it is shown that the samples of the experimental magnesium alloy, in comparison with the ML5 alloy, are more difficult to ignite and in most cases can self-extinguish rapidly, while the weight loss of the sample practically does not occur. |
