Residual Stresses01:26

Residual Stresses

1.1K
Residual stresses reside in a structure even after removing the original stress inducer. This phenomenon often arises from varied plastic deformations across different parts of a structure. Consider a rod stretched beyond its yield point. It will not regain its original length due to permanent deformation. Even after load removal, the rod does not entirely lose stress because of uneven plastic deformations, resulting in residual stresses. The computation of these stresses in structures is...

Nuclear Stability

20.5K
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Yield Criteria for Ductile Materials under Plane Stress

836
In designing structural elements and machine parts using ductile materials, it is crucial to ensure that these components withstand applied stresses without yielding. Yielding is initially determined through a tensile test, which evaluates the material's response to uniaxial stress. However, tensile stress is insufficient when components face biaxial or plane stress conditions This condition requires advanced criteria to predict failure.
The Maximum Shearing Stress Criterion, also known as...

Nuclear Fission02:50

Nuclear Fission

9.5K
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large...

Area of Science:

  • Materials Science
  • Nuclear Engineering
  • Additive Manufacturing

Background:

  • Additive manufacturing (AM) offers potential for nuclear reactor components.
  • 316 L steel is a candidate material due to its properties.
  • Microstructural stability is crucial for nuclear safety-critical components.

Purpose of the Study:

  • Investigate the microstructural stability of 316 L steel fabricated via Laser Powder Bed Fusion (L-PBF).
  • Assess changes from room temperature up to 650 °C.
  • Determine the onset temperature of irreversible microstructural phenomena.

Main Methods:

  • Laser Powder Bed Fusion (L-PBF) for sample fabrication.
  • Mechanical Spectroscopy (MS) tests for thermal cycling analysis.
  • Microstructural characterization (e.g., grain size, texture, vacancy recovery).

Main Results:

  • As-printed 316 L steel microstructure is unstable up to 650 °C.
  • Irreversible changes, including grain morphology and texture alteration, begin around 230 °C.
  • Observed phenomena include melt-pool pattern disappearance, equiaxed grain formation, cell size increase, and vacancy recovery.

Conclusions:

  • The microstructure of L-PBF 316 L steel undergoes significant, irreversible changes at temperatures below 500 °C.
  • These changes initiate at approximately 230 °C, contrary to existing literature.
  • Heat treatment is necessary to stabilize the microstructure before using this AM material in nuclear reactor components.
