Stress Relief Cracking of Ferritic Steels: Part Two

Known also by a range of synonyms, Stress-Relief Cracking (SRC) is intergranular cracking in the heat affected zone (HAZ) or weld metal that occurs during exposure to in-service temperatures or post-weld heat treatments.

Hot Cracking Sensitivity Factors

Identified by the appearance of liquid films along grain boundaries or to another location in the material structure, hot cracking can be divided into several categories.

Desulphurization of Nickel Base Super Alloys: Part One

Superalloys have been developed for key applications which typically require a combination of high temperature strength, toughness, and resistance to degradation in corrosive or oxidizing environments.
