Magnesium alloy components are norm

Magnesium alloy components are normally manufactured by
high-pressure die casting (HPDC) process because of good dimensional
accuracy, high production efficiency, and considerable
economic benefit. However, because of the nucleation in shot
sleeve, fast filling speed and high cooling rate in HPDC process,
various defects like gas pores (air entrapment), shrinkage pores
(solidification contraction), defect band and externally solidified
crystals (ESCs) exhibit in the final microstructure of die castings
[1–5], which greatly decreases the final mechanical properties of
the components.

Alloy magnesium komponente word gewoonlik vervaardig deur
High-druk Die beslissende (HPDC) Proses gevolg van goeie dimensionele
akkuraatheid, hoë produksie doeltreffendheid, en 'n aansienlike
ekonomiese voordeel. As gevolg van die nucleatie in geskiet
mou, vinnig vul spoed en hoë koel koers in HPDC Proses,
Verskeie defekte soos Gas porieë (Air verstrikking), krimp porieë
(Stolling inkrimping), defek Band en ekstern gestolde
kristalle (EGKS) Exhibit in die. finale mikrostruktuur van die giet
[1-5], wat grootliks verminder die finale Meganiese eienskappe van
die komponente.
