**4. Conclusions**

The tensile properties of the polycrystalline Cu6Sn5 were investigated at different temperatures and strain rates via the MD simulation. Based on the polycrystalline Cu6Sn5 created through Voronoi tessellation by Atomsk, the stress–strain curves at different temperatures and strain rates were obtained, from which Young's modulus and UTS were extracted. The stress–strain response could be affected by both the temperature and strain rate. The conclusions are as follows:
