Effect of Tin, Copper and Boron on the Hot Ductility of 20CrMnTi Steel between 650 °C and 1100 °C
High Temperature Materials and Processes, 2015 The hot ductility of 20CrMnTi steel with x% tin, y% copper and z ppm boron (x = 0, 0.02; y = 0, 0.2; z = 0, 60) was investigated. The results show that tin and copper in 20CrMnTi steel are detrimental to its hot ductility while adding boron can eliminate

Mechanical properties of Ultrahigh Boron Steels
Advanced Materials, 1995 A fine and stable grain size in steel results in greatly improved mechanical properties. In analogy to the addition of larger quantities of carbon to form ultra‐high carbon steels, the formation of borides in steel through rapid solidification and powder metallurgical techniques leads to the required grain size (see Figure) The materials processing ...

Mechanical Properties of Boronizing Steels as Repercussion of Boron Phases
Materials and Manufacturing Processes, 2009 Results of the boride surface layers investigation, obtained by the torsion and bending methods, point to the better ductility of the mono-phase Fe2B boride layers then the binary-phase FeB + Fe2B boride layers. This is especially outstanding in the case of peaces that are under higher thermal and mechanical load, where the binary-phase layer because ...

Review on the possible tool materials for friction stir welding of steel plates [PDF]
, 2014 The friction stir welding (FSW) process is mainly used in industrial applications for joining low melting temperature materials such as aluminium and magnesium. FSW has many advantages in comparison with conventional fusion arc welding.

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Effect of boron concentration on hot deformation behavior of stainless steel
Results in Physics, 2019 Steels with high boron content are important materials to produce spent nuclear fuel storage. The large volume fraction of brittle borides in the high boron steel microstructure makes it very hard and not easily deformable.
