Mechanical Characteristics of Steel01:18

Mechanical Characteristics of Steel

The mechanical characteristics of steel are assessed through various tests that evaluate its strength, toughness, and flexibility. These tests include tension, torsion, impact, bending, and hardness assessments, each providing crucial information about steel's suitability for specific applications.
The tension test is fundamental for determining tensile strength. In this test, a steel specimen is stretched using a gripping device until it breaks. The data collected during this test are used to...

Area of Science:

  • Materials Science
  • Additive Manufacturing
  • Mechanical Engineering

Background:

  • Selective Laser Sintering (SLS) is a key polymer additive manufacturing (AM) technique.
  • Conventional SLS is limited to polymer materials.
  • Manufacturing metallic components via AM often requires high-power lasers and specialized equipment.

Purpose of the Study:

  • To develop a metal-polymer composite for manufacturing metallic components using a low-power laser SLS system.
  • To investigate the feasibility of producing 17-4 PH stainless steel parts via this novel approach.
  • To characterize the mechanical properties and density of the resulting metallic components.

Main Methods:

  • A composite powder was prepared by mixing 17-4 PH stainless steel powder with polyoxymethylene (POM) and high-density polyethylene (HDPE).
  • Green parts were fabricated using a Sinterit Lisa SLS system (5 W, 808 nm laser) with optimized printing parameters (140 °C, 35.87 mJ/mm², 100 μm layer thickness).
  • The polymeric binder was removed via thermal degreasing, followed by high-temperature sintering (1310 °C for 180 min) to achieve a solid metallic component.

Main Results:

  • The SLS process successfully produced fully shaped green parts with a maximum density of 3.61 g/cm³.
  • Post-sintering, the metallic components achieved a density of 7.57 g/cm³ (97% of theoretical density) with an average shrinkage rate of 22%.
  • The final components exhibited a tensile strength of 605.64 MPa and a hardness of HRC 14.8.

Conclusions:

  • Low-power laser selective laser sintering of metal-polymer composites is a viable method for producing dense metallic components.
  • This technique offers a cost-effective, energy-efficient, and high-speed alternative for metal additive manufacturing.
  • The process accommodates a wide range of particle sizes, enhancing its applicability and reducing manufacturing costs.
