【摘要】：新一代耐磨材料Fe-C-B合金具有較高的經(jīng)濟(jì)效益和優(yōu)異的耐磨損性能,但網(wǎng)狀硼化物的存在導(dǎo)致其韌性較低,限制了其發(fā)展和應(yīng)用。闡述了Fe-C-B合金B(yǎng)含量優(yōu)化、高溫?zé)崽幚�、合金化、變質(zhì)處理等增韌方法的研究進(jìn)展。綜合大量研究發(fā)現(xiàn):B含量在2.0%~4.0%范圍內(nèi)時,合金性能較好,硬度可達(dá)到60HRC,沖擊韌性在6J/cm2左右;在1 000~1 050℃范圍內(nèi)進(jìn)行高溫?zé)崽幚砀诤辖鹪鲰g;合金化和變質(zhì)處理對韌性有一定改善作用。為了進(jìn)一步提高Fe-C-B合金韌性,需要結(jié)合各種增韌方法,深入探討韌性機(jī)制。
[Abstract]:The new generation wear-resistant material Fe-C-B alloy has high economic benefit and excellent wear resistance, but the existence of reticular boride leads to its low toughness, which limits its development and application. The research progress of toughening methods such as optimization of B content of Fe-C-B alloy, high temperature heat treatment, alloying and modification are reviewed. A large number of studies show that the alloy has better properties, hardness can reach 60HRC, impact toughness is about 6J/cm2, and high temperature heat treatment at 1 000 鈩，
