On February 28th, 2017, Professor Emeritus John J. Jonas was the recipient of the prestigious Acta Materialia Gold Medal. Along with a solid, 24 karat, gold medal, Prof. Jonas received a $10,000 USD cash prize. This award recognizes his seminal contributions to understanding phase transformations and dynamic re-crystallization in steel when it is red hot and flying through a rolling mill at 100 km/hr. In particular, his three major contributions relate to work in (1) dynamic and post-dynamic re-crystallization, (2) dynamic transformation and re-transformation and (3) the dynamic and strain-induced precipitation of carbonitrides in steel. This award is the latest of many prestigious honors that Prof. Jonas has been bestowed, his topmost prized, in order, include: the Order of Canada, The Acta Materialia Gold Medal, The Killam Prize for Engineering, the Order of Quebec, and the Quebec Prize for Science.
