NgoJulayi 13, 2023, iqela likaProf. Gang Wang kwiZiko loPhando lweZibonelelo kwiYunivesithi yaseShanghai lipapashe iziphumo zabo zophando zamva nje "i-Microstructural evolution kunye nepropathi yomatshini ye (FeCoNi)85.84Al7.07Ti7.09 ialloy ephezulu ye-entropy ngokunyibilika kwelaser ngokunyibilika ngonyango olugugayo", olusebenzisa inkqubo yokuvelisa ixesha elifutshane kakhulu ((FeCoNi)85.84Al7.07Ti7.09) i-alloy ye-entropy ephezulu. FeCoNi)85.84Al7.07Ti7.09 i-alloy ephezulu ye-entropy, ebonisa iimpawu ezigqwesileyo zomatshini, ezinamandla okugqibela e-1625 MPa, amandla esivuno se-1214 MPa, kunye nobude bekhefu le-11.6%. UNjingalwazi uJia Yandong kunye noGqr. Mu Yongkun ngababhali abahambelanayo.
Iziphumo eziphambili
Lo msebenzi uphande umphumo wonyango lokuguga kwi-microstructural evolution kunye ne-mechanical properties (FeCoNi)85.84Al7.07Ti7.09HEA eveliswa nguI-SLM. Kwenziwa ezi zigqibo zilandelayo.
(1) Iindlela ezimbini zokomeleza, ukomelezwa kokushenxiswa kunye nokomeleza imvula, zaziswa kwi-FCNAT HEA kusetyenziswa.I-SLMubuchule kunye nonyango lokuguga kwexesha elifutshane kuma-780°C. Ngenxa yoko, udibaniso lwe-high-density dislocations kunye nezigaba ze-precipitated zinokufezekiswa kwi-FCNAT 780, okukhokelela kwiipropati ezifanelekileyo zomatshini (isivuno samandla σ0.2, amandla okugqibela e-sUTS, kunye nobude kwi-break εf amaxabiso e-1214 MPa, 1625 MPa, kunye ne-11% ngokulandelanayo).
(2) Iziqendu zesigaba seI-SLMiisampulu kunye neesampulu ezindala zenziwe ikakhulu sisigaba seFCC, izigaba ze-L12 kunye ne-L21. Emva kokunyanga ukuguga, izigaba ze-L12 kunye ne-L21 zancipha kwaye umxholo wezigaba ze-L12 kunye ne-L21 zancipha ngokuthe ngcembe ngokunyuka kweqondo lokushisa lokuguga.
Ukuba ufuna ukwazi ulwazi oluninzi kwaye ufuna ukwenza imodeli yoshicilelo ye-3d, nceda uqhagamshelaneJSADD 3D Manufacturerngalo lonke ixesha.
