; Ni-based alloy; dissimilar metal laser welding 1 Introduction Hastelloy C-276 has been extensively used in petrochemical and nuclear power fields because of good corrosion resistance [1-3]. However... the mechanical properties of metal [10-12], especially the precipitated μ phase with stacking faults [13]. Welding is a wide hot working process. The study of secondary phases originated from the investigation......
on dissimilar metal and alloy systems [J]. Journal of Material Engineering Performance, 2010, 19(8): 1071-1089. [4] MISHRA R S, MA Z Y. Friction stir welding and processing [J]. Materials Science... characterization of dissimilar friction stir welded AA5083-H111 and AA6351-T6 aluminum alloys were studied. Three different welding speeds (36, 63 and 90 mm/min) were used to weld the dissimilar alloys. The effect......
distribution pattern, microhardness values of friction stir processed AA6061-T4 was investigated. 2 Experimental The base metal (BM) used in this work was the AA 6061 alloy with 4 mm thickness rolled... and the relation between the tool rotation direction and the welding direction [13]. It is apparent that the SZ exhibits a high degree of continuity and is not porous. Unlike that of the base metal (BM, Fig. 2......
of Mg/Al dissimilar clads 6 Conclusions 1) Multi-seam friction stir cladded Mg/Al composite plate exhibits saw tooth-like interface similar to explosive welding. This is due to the alternate arrangement.... Friction stir welding of dissimilar aluminium–magnesium joints: Sheet mutual position effects [J]. Science and Technology of Welding and Joining, 2015, 20: 271-279. [14] YAN Yong, ZHANG Da-tong, QIU Cheng......
by AFES et al [10]. MESHRAM et al [11] investigated the influence of interaction time on microstructure and tensile properties of the friction welding of dissimilar metal combinations. PAVENTHAN et al [12... dissimilar joints of austenitic stainless steel and copper alloy. Hence in this investigation, an attempt was made to optimize the friction welding parameters to minimize interface hardness......
