Abstract
Creep and rupture properties of three castings of MRI153 alloy, i.e. die casting, squeeze casting and ingot casting, have been investigated in a temperature range 150-200°C. The results showed that the squeeze-cast alloy has the highest creep resistance in terms of minimum creep rate or rupture time, while the die-cast alloy has the poorest creep resistance. The creep resistance of the three castings is discussed by considering the microstructural factors such as grain size, volume fraction of eutectic particles and degree of solute supersaturation as well as casting porosity.
