        abstract = {Tungsten-based alloys doped with the 10 wt\% FeCoNiCu medium entropy alloy (MEA) binder were fabricated by mechanical alloying. The role of the Cu-containing MEA binder and sintering temperatures (1250?1450?) on the synthesis, sintering behavior, and mechanical properties of the model tungsten alloys were investigated. The results demonstrate that the
solid-to-liquid phase transition during sintering was strongly infuenced by the presence of Cu in the binder and sintering
temperatures. A good combination of high compressive strength (2080 MPa), failure strain (42\%), and hardness (419 HV)
was achieved at the low sintering temperature (1250 ?), which promoted a fned grain structure with semisolid state sintering. However, Fe-rich oxide layers were formed along the grain boundaries at the high sintering temperature (1450 ?)
and caused a poor bonding strength between the binder phase and W matrix, thereby resulting in signifcant degradation of
mechanical properties}
