Anisotropy in impact toughness of powder bed fused AISI 304L stainless steel

Martensitic Transformation in Ultrafine-Grained Stainless Steel AISI 304L Under Monotonic and Cyclic Loading

The monotonic and cyclic deformation behavior of ultrafine-grained metastable austenitic steel AISI 304L, produced by severe plastic deformation, was investigated. Under monotonic loading, the martensitic phase transformation in the ultrafine-grained state is strongly favored. Under cyclic loading, the martensitic transformation behavior is similar to the coarse-grained condition, but the cycli...

Relaxation Peaks of Cold Worked 304l Stainless Steel

In this investigation internal friction of cold worked 304L austenitic stainless steel was measured and the new peaks (PlIP2,P3) were found. The height of those peaks increased with cold work degree. The temperature of the main peak P3 was 33513340K at the frequency of -1,000Hz. The activation energies and frequency factors were obtained from peak shift. The values were 0.4evl 0.4evl 0.6ev and ...

Effect of Crystallographic Orientation on the Pitting Corrosion Resistance of Laser Surface Melted AISI 304L Austenitic Stainless Steel

The localized corrosion behavior of laser surface melted 304L austenitic stainless steel was studied by potentiodynamic polarization test. The extent of improvement in corrosion resistance was governed by the preferred orientation and the percentage of delta ferrite present on the surface of the laser melted sample. It was established by orientation imaging microscopy that the highest pitting p...

Effects of powder recycling on stainless steel powder and built material properties in metal powder bed fusion processes

Micro abrasion-corrosion of AISI 316L stainless steel

In this study, the synergistic effects of abrasion and corrosion on AISI 316L stainless steel have been investigated using a micro-abrasion test rig. A series of results from abrasioncorrosion tests conducted using the micro-abrasion rig are presented. AISI 316L stainless steel has been studied under both pure abrasion and abrasion-corrosion conditions simulated by either distilled water or 3.5...
