Among the stainless steels, most widely used group is austenitic steels. The prominent reason why steels are preferred in welded steel fabrications their good weldability. AISI/SAE 304L exhibit adequate corrosion resistance oxidizing environments. also filling interfaces of runners between Tri-Nitro-Toluen vessel and ammunitions defense industry. For manufacture runners, plates pipes mainly joi...

The aim of this work is to derive the behavior for an austenitic single crystal from which the overall behavior of polynystalline TRIP steels can be deduced using classical scale transition method. The micromechanical modeling is based on the kinematics, kinetics and continuum-thennodynamics of the martensitic transformation. Plastic strains of product and parent phases as we11 as the volume fr...

Duplex stainless steel finds widespread use in various sectors of manufacturing and related fields. It has many advantages due to its distinctive structural combination austenite ferrite grains. is the need current generation better corrosive resistance over high production austenitic steels. This paper reviews weldability duplex steels, mentions reason behind for steels describes how it came i...

Herein, a comprehensive review on the application of digital image correlation (DIC) for investigations strain localization phenomena in field materials science and engineering (MSE) is provided. The Review divided into three parts. In Part 1, method DIC reviewed terms basic principles, algorithms, sources errors. 2 focused MSE. This part subdivided 1) combination with optical microscopy 2) sca...

Implantation using stainless steels (SS) is an example where an understanding of protein-induced metal release from SS is important when assessing potential toxicological risks. Here, the protein-induced metal release was investigated for austenitic (AISI 304, 310, and 316L), ferritic (AISI 430), and duplex (AISI 2205) grades in a phosphate buffered saline (PBS, pH 7.4) solution containing eith...

Duplex stainless steels (DSSs) with austenitic and ferritic phases have been increasingly used for many industrial applications due to their good mechanical properties and corrosion resistance in acidic, caustic and marine environments. However, DSSs are susceptible to intergranular, pitting and stress corrosion in corrosive environments due to the formation of secondary phases. Such phases are...

Today, a direct determination of the mechanical properties of complex alloys from first-principles theory is not feasible. On the other hand, well established phenomenological models exist, which are suitable for an accurate description of materials behavior under various mechanical loads. These models involve a large set of atomic-level physical parameters. Unfortunately, in many cases the ava...

Abstract Although martensitic transformation is neither necessary nor sufficient to explain hydrogen effects in austenitic stainless steels, the formation of a second phase upon straining results local strain incompatibilities within microstructure which can result assisted crack initiation. The fraction α’-martensite on fracture surfaces ten commercial steels different austenite stability was ...

The concept of the local approach is applied to investigate different damage mechanisms of structural steels by micromechanical material models. Static and dynamic fracture resistance curves for a neutron-embrittled weld material are derived from tensile and Charpy-type specimens with the modified Gurson model. The behaviour of a test piece with a crack in the fenitic base material beneath an a...

1 his paper provides a U-J;P,G work for selecting heat exchangers materials especially those used in nuclear power plants. Typical examples of materials selection for heat exchanger tubing of nuclear power plants and condensers are presented. The paper brings out also, the importance of continued intensive R & D in materials in order to enhance the reliability and reduce cost by improving upon ...
