Fatigue data for cast aluminum alloy
Fatigue data for cast aluminum alloy
(OP)
Hello,
can somebody recommend a source of decent fatigue data (Woehler-chart) for cast aluminum (I need it particularly for Al Si10 Mg). It should go up to at least 1...5*10^7 cycles. Thanks in advance!

Obtaining anything other than generic data on industrial alloys like 360 (equivalent to Al Si10Mg) is difficult. The die casting organizations (NADCA, etc.) and ASM Handbook Volume 2 provide fatigue strength data from rotating bending tests (R.R. Moore tests) usually at 5 x 108 cycles: for this alloy the data is 124-131 MPa. An S-N curve that I obtained from Lanxide (aluminum composites) shows A360 (lower impurity levels) maximum stress levels at 10[sup7 cycles of ~ 60-70 MPa under R=-1 conditions (fully reveresed). This data is more indicative of properties that can be obtained from production high pressure die castings, which will contain defects that suppress the fatigue life (entrapped gas porosity, filling defects, entrapped lubricant, etc.). The ASM data is best case, and therefore not conservative.
You may be able to find additional data by performing a review of published journals, technical papers, etc. The SAE Technical Paper series would be a good place to start, as well the research literature databases (Cambridge Scientific Abstracts, etc.). Use the following links for more information:
