GB/T 41739-2022 English PDF (GBT41739-2022)

This document specifies the test principle, samples, test devices and test procedure, test results, and test report for real-time detection of the dimensional stability of metal matrix composites using the thermal-cold cycle. This document applies to the determination for dimensional stability of aluminum matrix composites (thermal-cold cycling temperature range: 20 ¡ãC ~ 150 ¡ãC), magnesium matrix composites (thermal-cold cycling temperature range: 20 ¡ãC ~ 150 ¡ãC) and iron matrix composites (thermal-cold cycling temperature range: 20 ¡ãC ~ 490 ¡ãC).
