Effect of Zn on properties and microstructure of SnAgCu alloy
TL;DR: In this paper, the microstructures, wettabilities and mechanical properties of SnAgCu-xZn solders were investigated, and the results indicated that adding small amount of Zn can evidently improve the wettability, mechanical properties and refine the microstructure of lead-free solder.

The linear‐elastic Theory of Critical Distances to estimate high‐cycle fatigue strength of notched metallic materials at elevated temperatures
R. Louks,Luca Susmel +1 more
TL;DR: In this article, the authors investigated the accuracy of the linear-elastic theory of critical distances (TCD) in estimating high-cycle fatigue strength of notched metallic materials exposed to elevated temperatures during in-service operations.
Journal ArticleDOI
Notch Effect on Structural Strength of Components at Elevated Temperature Under Creep, Fatigue, and Creep-Fatigue Loading Conditions: Phenomenon and Mechanism
TL;DR: In this article, the effects of the notch on failure life of the components have been reported experimentally, including the strengthening and weakening effects; however, the internal mechanisms have not been clearly demonstrated.
Journal ArticleDOI
A new damage evolution model to estimate the creep fracture behavior of brazed joint under multiaxial stress
TL;DR: In this article, a new damage evolution model was put forward to estimate the creep fracture behavior of brazed joint under multiaxial stress and the influences of notch angle and radius were also discussed.
Journal ArticleDOI
Effect of notch position on creep damage for brazed joint
TL;DR: The results show that the different notch position and dimension generate different creep damage distributions and have a great influence on creep life.

Creep-Fatigue Life Evaluation for Sn-3.5Ag Solder
TL;DR: In this paper, the authors evaluated the creep-fatigue life evaluation of Sn-3.5Ag solder under push-pull loading using fast-fast, fast-slow, slow-fast and slow-slow strain waves.

A Strain Rate Ratio Approach for Assessing Creep-Fatigue Life of 63Sn-37Pb Solder Under Shear Loading
TL;DR: In this paper, a new method based on the strain rate ratio was developed, which predicted the creep-fatigue life within a factor of 4 scatter band, and the method was applied to the experimental data.
