Iron-based alloys with niobium (Nb), titanium (Ti), molybdenum (Mo) in combination with boron (B) and carbon have been selected as hardfacing alloys due to their high hardness and wear resistance gained by the precipitation of different abrasion resistant hard phases [15], [10].Cited by:   The microstructure and phase chemistry of a FeCrC wt% hardfacing alloy has been investigated using transmission electron microscopy and microanalytical techniques. The microstructure is found to consist of large primary M7C3. carbides in a eutectic mixture of austenite and more M7C3. The results indicate that the microstructure of the undiluted alloy becomes Cited by: Present study is based on the variation of micro-hardness, microstructure and abrasive wear resistance by coating of Fe-Cr-C-X%B. Six different compositions are used for the coating on mild steel.   Read "Wear behavior–hardness–microstructure relation of Fe–Cr–C and Fe–Cr–C–B based hardfacing alloys, materials & design" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.

The methodology was based on correlation between the microstructures of arc welding hardfacing deposits and their wear resistances. To obtain deposits of high Cr white cast iron (Fe-Cr-C alloys) with different microstructures, a modification of the self-shielded flux cored welding (S-FCAW) process was designed, the weld pool was fed withCited by: 1. Fe-based alloys such as Fe–Cr–C are well known for their excellent performances under severe wear conditions [5]. The microstructures with Fe–Cr–C alloy have either hypoeutectic, eutectic. alloys for advanced reactor applications. The research is based on neutron irradiation experiments on a matched set of ferritic alloys in a high flux test reactor. The irradiation exposures have been completed (see the table below) – the objectives of this proposal are to: (1) perform post-irradiation analysis of . The bioresorbable material “metal” is more advantageous in cardiovascular application over polymers and ceramic due to their remarkable properties including high impact strength, high ductility, and high strain energy. In this chapter we glance over the cardiovascular applications of metals including heart valves, stents, pacemaker, etc.

Laser rapid-alloy prototyping for the development of wear resistant Fe–Cr–C/NbC composite materials Article in Journal of Laser Applications 15(4) November with 20 Reads. Alloys in the Fe Ni Cr C system have been chillblock melt spun to form lath martensitic (α′), austenitic (γ) or γ + M 7 C 3 ribbons. As-cast hardnesses range from about H k for α′ ribbons to about H k for low-carbon γ by: 6.   A study was carried out on the impact toughness of Fe- Cr- Х damping alloys. Two measures proved to be effective in improving impact toughness. One was to lower carbon plus nitrogen content to an ultra- low level. This method is suitable for single- phase ferrite alloy. The other is to use dual- phase damping alloys. The presence of martensite in Fe- Cr- Х alloys can enhance impact Cited by: 1. Because refractory metals are a class of materials possessing extraordinary high-temperature properties, they are perennial contenders for high-temperature nuclear applications. However, their use to date has been limited, due in part to the difficulty in fabricating high-performance refractory parts and their environmental degradation including irradiation effects.
