Summary

This paper investigates the microstructure evolution during spark plasma sintering (SPS) of FJS 1 lunar soil simulant. The study examines the effects of SPS conditions on densification, phase transformation, and mechanical properties. The FJS 1 simulant is composed of sodian anorthite, augite, pigeonite, and iron titanium oxide. The results show that SPS significantly enhances densification and microhardness compared to pressureless sintering. This paper investigates the feasibility of spark plasma sintering (SPS) for densifying FJS 1 lunar soil simulant. The study examines microstructural evolution and mechanical properties under varying SPS parameters. FJS 1 is a commercial lunar soil simulant used in lunar studies. The SPS process involves high temperature (1100 C), pressure (25 MPa), and vacuum conditions. The simulant's chemical composition and particle size distribution are comparable to real lunar soil. This paper investigates the microstructure evolution of FJS 1 lunar soil simulant during spark plasma sintering (SPS) and pressureless sintering (PLS). The study compares the effects of different sintering temperatures and pressures on the phase and microstructural changes of
