Abstract: This paper investigates long fatigue life characteristics of AlSi10Mg and AlSi7Mg aluminium alloys produced using direct metal laser sintering. An inhouse built ultrasonic fatigue testing machine was used to carry out fatigue tests on specimens machined from heat-treated AlSi10Mg and AlSi7Mg alloys subjected to constant fully reversed tension-compression loadings. The fatigue life data acquired for these two additive manufacturing (AM) aluminium alloys were compared with previously published data under heat tr… Show more

“…The effects of surface roughness on the low-cycle [ 31 ] and high-cycle fatigue [ 32 ] life are not a negligible parameter for a different type of metal alloy due to the crack initiation period [ 33 , 34 , 35 ]. Certainly, the behavior of materials during low-cycle fatigue will have an effect, as well as a heat treatment effect [ 32 ], anisotropy, grain characteristics, defects, surface roughness, and residual stresses [ 36 , 37 ].…”

“…6,7 Although torsional 8 and three-point bending multiaxial 9 ultrasonic fatigue tests were later developed, high-frequency uniaxial tension-compression fatigue testing studies are more studied in the literature. [10][11][12] Ultrasonic fatigue tests are generally carried out on specimens of sufficient length to resonate in ultrasonic frequency. Methods for the ultrasonic fatigue testing of various designs such as cruciform specimen 13 -biaxialand even thin sheets have also been developed.…”
