Shuyang participated in UConn SoE poster presentation on 03/11/2020. The presentation title was “Mechanical behavior of uniaxial compression of SrNi2P2“.

This work discussed his recent experimental results on the ultrahigh superplastic strain and fatigue resistance in SrNi2P2 intermetallic compounds. SrNi2P2 shows 18% of elastic strain and survives over 10,000 cycles of superelastic deformation! Double lattice collapse is the main mechanism of superplasticity. This is certainly a new discovery!
