Thermo-mechanical fatigue property of a surface-hardened AC4B cast aluminum alloy

The Effect of Various Parameters on Out-of-phase Thermo-mechanical Fatigue Lifetime of A356.0 Cast Aluminum Alloy

In this paper, the effect of various parameters on out-of-phase thermo-mechanical fatigue (OP-TMF) lifetime of A356.0 cast aluminum alloy is investigated. The studied parameters include maximum temperature, dwell time, and the thermo-mechanical loading factor. OP-TMF tests are conducted considering realistic running conditions of diesel engine cylinder heads. The maximum temperature varies betw...

Failure Analysis of a Cast A380 Aluminum Alloy Casting Using a Microstructurally Based Fatigue Model

When evaluating the fatigue life of a die cast A380 aluminum alloy, the combination of microstructures, inclusions, and stress concentrations is particularly important. This paper presents a failure analysis of an A380 die cast aluminum pivot arm used in a clothing press. This study includes finite element analyses, optical microscopy of the fracture surface, fatigue testing of the A380 aluminu...

Cast Aluminum Alloy for High Temperature Applications

Originally developed by NASA as high performance piston alloys to meet U.S. automotive legislation requiring low exhaust emission, the novel NASA alloys now offer dramatic increase in tensile strength for many other applications at elevated temperatures from 450°F (232°C) to about 750°F (400°C). It is an ideal low cost material for cast automotive components such as pistons, cylinder heads, cyl...
