Effect of Subsequent Heat Treatment on Microstructure, Hardness, and Corrosion Behavior of Extruded and Swaged Mg0.15Ca
(2025) Magnesium Technology Symposium, 2025, held as part of the TMS Annual Meeting and Exhibition, TMS 2025 In Minerals, Metals and Materials Series p.11-21- Abstract
In this preliminary study, the influence of a subsequent heat treatment after extrusionExtrusion and swagingSwaging on the microstructureMicrostructure, hardness, and corrosionCorrosion behavior of Mg0.15Ca was investigated. Heat treatment was carried out at 300, 400 and 500 °C for 1 h, and 16 h at 500 °C. Immersion in HBSS and Ringer's solution was done for up to 7 days. With increasing heat treatment temperature and time, the grain size increases, the hardness decreases, and the corrosionCorrosion rate increases. Swaged Mg0.15Ca corroded stronger in Ringer's solution—however, more uniform and still with low corrosionCorrosion rates, which are known from Mg0.15Ca. CorrosionCorrosion in HBSS led to pitting, which was more pronounced at... (More)
In this preliminary study, the influence of a subsequent heat treatment after extrusionExtrusion and swagingSwaging on the microstructureMicrostructure, hardness, and corrosionCorrosion behavior of Mg0.15Ca was investigated.

With increasing heat treatment temperature and time, the grain size increases, the hardness decreases, and the corrosionCorrosion rate increases. Swaged Mg0.15Ca corroded stronger in Ringer's solution—however, more uniform and still with low corrosionCorrosion rates, which are known from Mg0.15Ca. CorrosionCorrosion in HBSS led to pitting, which was more pronounced at high annealing temperatures. An influence of residual surface stresses from swagingSwaging is expected. Heat treatment at 300 °C shows the highest resistivity to pitting corrosionCorrosion. The coarse-grained microstructureMicrostructure shows signs of intergranular corrosionCorrosion as well as transgranular fracture.
