Strengthening mechanisms in Elgiloy

Journal of Materials Science, 1984
The effects of cold-working and age-hardening on the microstructure of Elgiloy (composition in wt %, 40 Co, 20 Cr, 15 Ni, 7 Mo, 2 Mn, 0.1 C, balance Fe) have been established. 36% and 72% cold reduction of the solution treated (ST) alloy (f c c) produced a network of thin f c c deformation twins and h c pe-martensite platelets.

Strengthening mechanisms in alloys

Proceedings of the Indian Academy of Sciences Section C: Engineering Sciences, 1980
Metals can be strengthened by methods appropriately combined to meet the operating conditions. In this ‘alloy design’, effort, we are guided by semi-quantitative relations that have been developed over the years and which relate the efficacy of the strengthening methods to the deformation modes.
