The relation between the microstructure and mechanical properties of Fe–Nb dissimilar joint were investigated using nanoindentation. weld metal consists mainly Fe2Nb, α-Fe + Nb (s,s) Fe7Nb6 phases. Radial cracks initiate from corners impressions on Fe2Nb phase (~20.5 GPa) when subjected to a peak load 300 mN, whereas fine lamellar structures (α-Fe Fe2Nb) with an average hardness 6.5 GPa are fre...
Dissimilar material joining between magnesium (AZ31B) alloy and dual-phase steel (DP600) was achieved using the friction stir welding (FSW) process. The present work aimed at studying effect of tool rotational speed on microstructure mechanical properties dissimilar joints. joints were fabricated speeds 800 1600 rpm with weld 50, 100, 150 mm/min, respectively. plunge depth 0.2 mm tilt angle 2° ...
In this research, dissimilar welding of NiTi shape memory alloy to AISI 304 austenitic stainless steel Archwires was investigated. For this purpose, common straight orthodontic archwire with rectangular cross-section and dimensions of (0.635 × 0.432 mm) were selected and the laser welding technique was used to connect the wires. The microstructure, chemical composition and phasesin the weld zon...

In the present Study, a dissimilar joint of carbon steel sheet EN 10025 with 316 L has been welded by FSW and the welding parameters were optimized by RSM software method. For investigation of mechanical properties and microstructural analysis carried out by using optical, scanning electron microscopes with EDS analysis, tensile and hardness test of different area of joints, SZ, TMAZ, HAZ, thei...
Abstract Welding of dissimilar metals is one the most substantial requirements industries and extensively used in engineering applications. Dissimilar friction crush welding between oxygen-free copper (C1020) aluminum (1145-H1) sheets with a thickness 1 mm was investigated this work using different flange edge heights (2, 2.5 3 mm) gaps (0.5 Cu-Al sheets. Tool rotational speed 1500 rpm feed rat...
