Mechanical Properties of Aluminum Alloys under Low-Cycle Fatigue Loading

Martensitic Transformation Under Loading and the Mechanical Properties of Iron Alloys

The ma~tensitic transfol-niation (MT) under tensile dcfol.m:ltion at 77K i n a series of FeNi-Mn alloys was studied. The anlotult of ~na~tensite fos~ned d ~ ~ r i ~ l g the tensile test depends on the applied stress and on the Mn content which determines the mnrtensitic point and the MT start stress. Elongation of the tensile tested samples has a maximum value in the alloys co~ltainilig the 50%...

Low Cycle Fatigue Testing of Ball Grid Array Solder Joints under Mixed-Mode Loading Conditions

To give a proper and accurate estimation of the fatigue life of ball grid array (BGA) solder joints, a mechanical fatigue test method under mixed-mode loading is proposed. Experiments were conducted with 63Sn/37Pb and Sn/3.5Ag/0.75Cu solder joints in room temperature. The mechanical low cycle fatigue tests were performed under several loading angles. The loading angle is controlled by several g...

Linkage between Ductile Fracture and Extremely Low Cycle Fatigue of Inconel 718 under Multiaxial Loading Conditions

Ductile fracture and extremely low cycle fatigue (ELCF) [1] are two common failure modes in aircraft engines and turbomachinery designs [2]; however, the linkage between these two failure modes under multi-axial loading conditions has never been systematically studied. Inconel 718 (IN718) is one type of high temperature alloys widely used in turbomachines. Specially designed specimens and tests...
