| Abstract: |
Creep is an important design consideration in many engineering applications from aeroengines to soldered joints in electronics. The materials used in each of these applications vary depending on their design requirements and this article describes the phenomenon of creep in many of these materials. The high temperatures reached in gas turbines require the temperature capabilities of nickel-based alloys. The creep behavior of these “superalloys” is described, highlighting how these alloys can withstand such harsh operating conditions. For applications where low weight is important, but good creep resistance is required, titanium alloys are widely used. The creep of both conventional and titanium aluminides is described. For engineering applications where components do not operate at extreme temperatures, creep can still be important. Aluminum and magnesium alloys are widely for lightweight components due to their low densities and good strength. However, creep in these alloys can occur at temperatures below 300°C, and as such the creep behavior of these alloys must be understood. This article also describes creep in lead-based and lead-free solder, where low melting points can result in creep at temperatures below 100°C. Finally, copper and its alloys have been widely used for creep experiments and the creep behavior of these materials has been described. |
