The structure and chemical composition of the passive film formed on 17-4PH martensitic stainless steel (MSS) manufactured by powder bed laser beam melting (LBM) were investigated combining XPS TEM analyses, comparison to a conventional 17-4PH. was found similar for both MSSs, with, matrix, duplex layer composed Fe Cr oxy-hydroxide followed an intermediate enriched in metallic compounds. A part...

Nuclear and cytoplasmic morphological changes provide important information about cell differentiation processes, cell functions, and signal responses. There is a strong desire to develop a rapid and simple method for visualizing cytoplasmic and nuclear morphology. Here, we developed a novel and rapid method for probing cellular morphological changes of live cell differentiation process by a fl...

The purpose of this research was to analyze and compare the mechanical properties of parts made using both Direct Metal Laser Sintering (DMLS) and traditional manufacturing methods like casting or forging. Previous research in DMLS was conducted using various materials, but there has been very little done for 17-4PH stainless steel. All the samples used for testing were conducted using the EOSI...

As a high-strength corrosion-resistant alloy, stress corrosion cracking (SCC) behavior is key consideration for the conventional, wrought form of 17-4PH stainless steel. With increasing popularity additively manufactured (AM) 17-4PH, understanding SCC AM will be similarly critical its presumed, future applications. The current study quantifies and compares both form, as baseline, at peak-aged (...
