“…CBS had lower impact strength compared to DBS. In CBS, titanium fixes nitrogen by forming TiN precipitates and free boron in solution segregated to austenite grain boundaries, reduces the cohesive force and thereby impact toughness (Kapadia, et al 1968;Azarkevich, et al 1995). However, in DBS titanium presence was in traces, boron reacts with nitrogen and carbon to form precipitates of boron nitride and boron carbide respectively.…”

Boron Steel: An Alternative for Costlier Nickel and Molybdenum Alloyed Steel for Transmission Gears

Case Carburized (CC) low carbon steels containing Ni, Cr and Mo alloying elements are widely used for transmission gears in automobile, as it possesses desired mechanical properties. In order to cut cost and save scarce materials like Ni and Mo for strategic applications, steel alloyed with Boron has been developed, which gives properties comparable to Ni-Cr-Mo alloyed steel. In the process of steel development, care was taken to ensure precipitation of boron which results in precipitation hardening. The characterization of the developed boron steel had exhibited properties comparable to Ni-Cr-Mo alloyed steel and superior to conventional boron steel.

“…Boron is used in steels, principally to improve hardenability. For this, the benefit is only derived when in solution in the austenite [14,15]. Its solubility in both ferrite and austenite is very low; for example, in austenite at 900 • C, it is only ~0.003% [16].…”

In this paper, the influence of small additions of Cr, Mo, Cu, Ni, B, Ca, Zr, and Ce on the hot ductility of advanced high-strength steels (AHSS) has been reviewed. Most of these small additions have a positive effect in improving hot ductility on straightening during continuous casting operations and should be considered when problems with cracking in continuous casting are encountered. In many of these cases, the reason for these generally small but important improvements in hot ductility is not known with certainty, but the segregation of these elements to the austenite grain boundaries, strengthening the bonding, is often suggested.

“…These borides are extremely hard [11] and thus able to protect the ferrite/austenite matrix enhancing wear resistance especially against abrasion. Since boron has limited solubility in ferrite and austenite [12,13], the formation of borides takes place during solidification. An advantage over typical heat treatments for precipitation of hard particles is that once borides are formed in the steel matrix, they remain unaltered because they do not undergo solid-state transformations.…”

Two duplex stainless steels 2205 and 2205 with 2.5 wt-% B addition prepared by a fast solidification technique were investigated. The samples were arc melted and cast in a cylindrical mould with varying diameters in a single cavity that provided different cooling rates. The hardness increased in both cases for smaller diameters, however, there was a different profile from the surface to the centre in case of 2205 with 2.5 wt-% B. The microstructural investigation indicated that boron addition led to the formation of hard borides and grain refinement. Different boride morphologies that varied with the cooling rates were identified. The compression strength at room temperature improved by a factor of 3.5 with boron addition without considerably decreasing the ductility.
