In this paper, through the relevant experiments, the effect of rare earth on the microstructure and properties of high carbon steel is studied. The experimental results show that rare earth with content of 0.014 5% can significantly reduce the size of pearlite pellets and pearlite lamella spacing ...
Carbon steel, as you can probably gather from the title of this article, comes in forms graded by their specific carbon content. Low-carbon steel is that which contains less than 0.25 percent of carbon; medium-carbon steel contains 0.25 percent to 0.55 percent carbon; and high-carbon steel i...
The microstructure and properties of ultra-high carbon steel (UHCS) was investigated. The results indicate that ultra-fine spheroidized carbides were formed by complete austenizing with high temperature tempering, and ultra-fine martensite or pearlite could be formed when the steel was then heated ...

Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world’s infrastructure and industries, it is u
First investigations of surface hardened steel in the very high cycle fatigue (VHCF) regime [1], [2] show S–N curves with a plateau-like regime in the range of 106 load cycles, however fatigue failures occur and the S–N curve decreases with significant slope at numbers of cycles ...
From bustling urban sidewalks to high-speed highways, safety barriers play a crucial role in managing vehicle traffic and protecting people and infrastructure. Two of the most common solutions are bollards and Jersey barriers. While both serve to prevent accidents and provide perimeter protection, they...
Oxygen, a colorless, odorless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen forms
Cadmium, chemical element, a metal of Group 12 of the periodic table. Most cadmium produced is electroplated onto steel, iron, copper, brass, and other alloys to protect them for corrosion. Cadmium is physically similar to zinc but is denser and softer.
This result is ascribed to the reduction in the carbon stoichiometry of the powder. The compositions of the carbides in the powder were not fully stabilized until they had been sintered (i.e., longer exposure to a high temperature than powder). This is due to the different formation kinetics...
