ABSTRACT
How to judge magnesium alloys ignition point accurately was a problem needed to be solved. A Traditional method with a thermocouple influenced the distribution of measured temperature field, which had a slow response speed and was difficult to shrink and automate. To address the above problems, a small colorimetric temperature measurement system was designed and its composition and operating principle were introduced; using a mutational site in optical radiation power received by temperature-measuring system was presented to determine the time when magnesium alloy began burning; moderate temperature blackbody furnace was utilized to calibrate statically to obtain static calibration coefficient; electrical heating slice resistance was presented to ignite magnesium alloys, which had advantages of simple operation, saving time and test materials; SCM was employed in data-processing; this system was portable, exquisite and reliable. The ignition test result of AZ80 with 0.75% Nd shows that, the results of colorimetric temperature measurement system and infrared thermometer are 873.9 and 879.1, respectively, the relative error is 0.6%, which verifies the feasibility of this method.
