TL;DR: In this article, the authors investigated the influencing factors on mechanical property stability of Cu-Mo-Ni alloyed austempered ductile iron (ADI) and showed that after austenitized at 900 ℃ for 2 h followed by austenpered at 370 Ω for another 2 h, the mechanical property of the alloyed ADI can reach the Germanite GGG-100 standard, i.e.σb≮1 000 MPa, δ≮5%, at 95% confidence level.

TL;DR: Zhang et al. as discussed by the authors reported a 0.5wt% Ca for AZ91, which is the smallest percentage of the population in the world, in the last decade.
