Effect of titanium on the ductilization of Fe–B alloys with high boron content

Influence of the Ratio Ti/B on the Microstructure and Hardness of Steel With High Boron Content

“…Пос-леднее свойство определяется микроструктурой и фазо-вым составом литых полуфабрикатов. В работах [1,2] показано, что добавление титана в количестве одного атома на каждый атом бора (массовое соотношение Ti/B = 2,7) положительно сказывается на пластичности стали при комнатной температуре как в литом, так и в горячекатаном состоянии. Это в основном связано с из-мельчением зерна и уменьшением размера боридов [3], а также с образованием диборидов титана (TiB 2 ) вмес-то боридов железа и хрома (Fe, Cr) 2 B [4, 5] благодаря большей термодинамической стабильности первых [6,7].…”

Effect of La2O3on microstructure and properties of Cu20Fe80alloy by microwave sintering

“…But the traditional bearing mixed iron copper powder, the compressive strength, hardness is based on copper based materials on the increased slightly, poor corrosion resistance, and will inevitably generate and microstructure segregation caused by inhomogeneity of hard phase and the performance of the resulting running noise increases and shorten the service life of the bearing, the in the large-scale automation production process, is not conducive to ensure the consistency and stability of the product performance [4][5][6][7] . In this paper, La 2 O 3 was added in the preparation of Cu-Fe alloy, and the effect of La 2 O 3 on the microstructure and properties of Cu-Fe alloy during mechanical alloying and cold pressing microwave sintering was studied.…”

Study on mechanical properties and microstructure of Cu20Fe80alloy using the mechanical alloying

“…The inhomogeneity caused the performance of the bearing in the operation noise increased and shortened service life [4][5][6][7]. In this paper, the preparation method of the combination of mechanical alloying, cold pressing and microwave sintering is proposed.…”
