NEW TREATMENT ROUTE FOR CLOSED-DIE FORGINGS OF STEELS WITH 2.5% MANGANESE

On the Step Cooling Treatment for the Assessment of Temper Embrittlement Susceptibility of Heavy Forgings in Superclean Steels

When subjected to extended exposure to intermediate service temperatures, Cr–Mo steels, Ni–Cr steels, and 5% Ni steels can become embrittled, with an associated decrease in fracture toughness and a shift in the ductile-to-brittle transition temperature to higher temperatures. Two methods for the investigation of temper embrittlement phenomena are isothermal aging or the use of a step cooling ag...

Austenitic Manganese Steels – Developments for Heavy Haul Rail Transportation

In 1882, Sir Thomas Hadfield patented an alloy with quite remarkable properties. Its composition was Fe-1.3%C-13%Mn and it was the toughest alloy known! The claim has stuck for the century since then and the alloy is now used universally for the “frog” in railway crossings in countries such as Canada where heavy loads are moved by rail using high axle loading. In fact, the alloy is very soft wh...

Analysis of Compression Creep Deformation of 7050 Aluminum Large Scale Open Die Forgings during the Solution Heat Treatment Process

Acknowledgments We would first like to acknowledge everyone who helped us complete our senior project. Professor Blair London, our senior project advisor, for giving us guidance throughout the year. Kyle Logan for meeting with us weekly to assist in our progress and guide us through problems and Mark Timko for offering advice with certain obstacles, both who were our sponsors from Weber Metals....
