Status and Progress of Super-Bainitic Steels

Teshugang, 2012
The basic alloying elements in super-bainitic steels are C-Mn-Si and the structure of ultra-fine bainite, martensite and residual austenite is obtained by low temperature phase transformation at 300 〜500 ℃. In order to decrease critical cooling velocity,

Regulating the Boron Content to Suppress Stress‐Relief Cracking in the Coarse‐Grained Heat‐Affected Zone of 7CrMoVTiB10.10 Heat‐Resistant Alloy

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

STRUCTURE OF MODERN RAIL STEELS. BAINITE STEELS

, 2022
Metal science attracts attention by the fact that it is constantly necessary to look for non-standard solutions. This also applies to materials used to improve the quality of operation of railway rolling stock. Since quality is always associated with safety, when improving the quality of rolling stock, one should not forget about the quality of the ...
