The LMDed SS304 specimens are fabricated by the same combination of the process parameters so that they have the similar properties. The microstructure is similar to that of the selective laser melted (SLMed) specimen. The grain sizes of the LMDed specimen are compared with those of the ...
SS304 stainless steelIn-phase (IP) and out-of-phase (OP) thermomechanical fatigue (TMF) properties of SS304 stainless steel were evaluated in the temperature range of 300–600 °C. All tests were strain controlled and the strain rate was kept constant. Material exhibited cyclic hardening ...
A transition layer was designed to compensate for the dilution of Cr and Ni in stainless steel layer during the welding of dissimilar metals. From the results, it was seen that the lowest hardness of fusion weld was located in transition layer, followed by 304L stainless steel side, and the...

Superelastic NiTi alloy and 304 stainless steel (304 SS) were joined with a Cu interlayer by ultrasonic spot welding (USW) using different welding energy inputs. The surface morphology, interfacial microstructure, mechanical properties, and fracture mechanisms of the dissimilar NiTi/304 SS USWed join...
From the correlation between the microstructural and mechanical properties, shear strength of approximately 35MPa for graphite-304SS-brazed joint produced at 900°C was demonstrated. After the shear tests, the fracture surfaces were analyzed by SEM-EDS. 展开 ...
HL Sang,TS Yong,HW Lee - 《Journal of Korean Institute of Metal & Materials》 被引量: 2发表: 2012年 EXPERIMENTAL INVESTIGATION ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF DSS2205 AND SS304L DISSIMILAR WELDMENTS This paper outlines the TIG welding process without using active flux for 4...
Austenitic Stainless steels are sensitized when exposed to elevated temperature range of 470-750°C causes carbide precipitations at grain boundaries. Carbide precipitation can have deleterious effects on the resistance to intergranular corrosion and reduces the tensile properties of stainless steels, specifi...
The EDS analysis conforms the well mixing of SS and Cu inside the weld pool. The mechanical properties in terms of tensile stress found up to 201 MPa and the fracture are obtained outside the weld zone. Microhardness measurements over the fusion zone have been done to understand the ...
Adding Ni as filler material is one of the effective methods to restrain the cracks in laser-welded joints of NiTi/ stainless steel (SS), while the formation of Ni3Ti at the NiTi/Ni interface result in uneven distribution of the microstructure of the joint, which limits tensile strength of...
