Compositionally graded cylinders comprising FeCo-2V, a soft magnetic alloy, and 316L stainless steel, were produced by directed energy deposition incorporating two different gradient lengths. Five distinct regions in the microstructure observed both as-printed annealed gradients. When normalized for length, gradients showed similar grain size microhardness profiles. In tensile tests, samples fa...

The relation among microstructure and fatigue behavior of 2205/316L stainless steel dissimilar welded joints was investigated. Plates 6.35 mm in thickness with a single-V joint configuration were gas metal arc (GMAW) single pass by feeding at 6 m/min an ER2209 filler wire heat input 1.2 kJ/mm. Grain growth the high temperature-heat affected zone (HT-HAZ) occurred mostly mid-height plates, delim...

simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...

in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...
