Based on the conceptual model of strain energy density, Mirsayar predicted the direction and rate of FCG caused by the anisotropy of additive manufactured parts. With the anisotropy of the microstructure, it is expected that the fatigue performance and HE mechanism of SLM 304L will be different from that of wrought 304L. SLM 304L has a higher yield strength, which is about twice that of wrought 304L, and at the same time has better plasticity, achieving a strength-plasticity balance. Due to the extremely fast cooling rate, the material has a fine microstructure, thus achieving excellent mechanical properties. By properly adjusting the forming parameters, such as laser power, scanning strategy, and hatch spacing, SLM manufactured parts with a relative density greater than 99%. Compared with the wrought metal material process, the SLM forming process has the advantages of high design freedom, no subsequent processing steps for the formed parts, and reduced material waste. Selective laser melting is one of the most widely used additive manufacturing technologies. In addition, 304L has low strength, which greatly limits its application in the field of hydrogen.Īdditive manufacturing is a new material-forming technology that can rapidly form complex near-shape parts by printing layer by layer without the need for templates. However, 304L still cannot meet the requirements of stable and anti-HE in the actual high-pressure hydrogen environment. Some studies have improved its resistance to HE through surface carburization and warm rolling, , and the FCGR has even decreased by an order of magnitude. As a metastable austenitic stainless steel, 304L is more susceptive to HE. (1) α′ martensite is easily generated at the intersection of slip bands and deformation twins under cyclic loading, then the interaction between hydrogen and α′ martensite will accelerate fatigue crack growth rate (FCGR) of the material (2) hydrogen can promote dislocations movement and lead to local plasticity of the material (3) hydrogen can also reduce the bonding force between atoms, leading to premature failure of stainless steels.ģ04L stainless steel (304L) has good corrosion resistance, mechanical and processing properties. A large number of studies have explained the HE mechanism of wrought austenitic stainless steels. However, in the actual production and use process, even if there is no load case, the mechanical properties of the austenitic stainless steel in a hydrogen environment will be reduced, resulting in macroscopic low ductility fracture, which is called hydrogen embrittlement (HE). Austenitic stainless steel is often used as a hydrogen storage material due to its lower hydrogen diffusivity and higher hydrogen solubility, such as high-pressure hydrogen pressure vessels, valves, and hydrogen fuel cell automobile parts. 1.Hydrogen as clean energy can replace traditional fuel, is gradually becoming the main energy carrier in the world, and is widely used in various fields. Legal Alternatives to Adobe Illustrator CC 2017 CrackĪre you aware of all the possible risks of Adobe Illustrator CC 2017 Crack and don’t want to get into trouble using pirated programs? Read on and I will tell you how to get Adobe Illustrator in a legal way. Unfortunately, such privilege is not available for you in case you use unlicensed software, like Crack Adobe Illustrator CC 2017. When you have an illegal version, lags and bugs are of common occurrence and you will need qualitative assistance more than ever. Of course, you pay for Illustrator itself and for the assistance you might need while operating the program. If you don’t know what you pay for getting a legal subscription, I will explain it to you in short. In addition, cracked copies are not as fast as original ones, and some features in them are deactivated. Therefore, many errors appear, resulting in the freezing of programs and the whole OS. In order to receive Adobe Illustrator 2017 Crack, hackers break the program code of the official version. Therefore, downloading pirated programs and trying to save several bucks, you might pay a hundred times more. As a result, they may be fined or taken to prison. ![]() Although the installation or usage of illegal copies such as Adobe Illustrator Crack is a law violation, many users still rely on cracked software.
