Hot cracking in ZK60 magnesium alloy produced by laser powder bed fusion process

Biodegradable magnesium alloy WE43 porous scaffolds fabricated by laser powder bed fusion for orthopedic applications: Process optimization, in vitro and in vivo investigation

“…Despite the difficulties, L-PBF of Mg alloys has made great progress in the latest decade [ [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] ]. Ng et al firstly attempted L-PBF of pure Mg in 2010 [ 32 ].…”

“…Wei et al investigated the effect of vaporization on compositional change by using AZ91 and ZK60 alloys [ 34 , 35 ]. Massive hot cracks were observed during the L-PPBF of ZK60 and JDBM alloys [ 36 , 37 ]. Hot cracking was seldom observed during the L-PBF of WE43 alloy owing to the relatively narrow solidification temperature, however, massive precipitation phases including MgRE compounds and RE oxides were found in WE43 L-PBF parts.…”
