摘要:

隨著科技的發(fā)展，機(jī)械加工對高速刀具的需求進(jìn)一步提高，傳統(tǒng)高速鋼生產(chǎn)的短板也逐漸顯露出來。由于高速鋼中高合金元素含量的特性，傳統(tǒng)高速鋼生產(chǎn)方式主要以模鑄為主，雖然產(chǎn)品質(zhì)量相對較好，但是生產(chǎn)效率極慢。連鑄可以顯著提高高速鋼的產(chǎn)量并且更加節(jié)能，但連鑄生產(chǎn)的高速鋼鑄坯中心縮孔較大，并且軋制過程中開裂的問題一直無法解決，因此高速鋼連鑄一直無法正式投入生產(chǎn)。碳化物是影響高速鋼性能的一個(gè)非常重要的因素，添加合金元素會(huì)對高速鋼中碳化物尺寸、形貌以及元素組成產(chǎn)生影響，從而改善高速鋼性能。合金元素按照作用方式不同可以分為碳化物形成元素以及非碳化物形成元素，這兩類元素對碳化物有著不同改性效果，并且作用機(jī)理有較大差異。討論了高速鋼中碳化物的主要種類，針對不同種類的合金元素總結(jié)了其對高速鋼中碳化物的作用以及研究現(xiàn)狀，并對未來合金元素在高速鋼碳化物改性方面的研究提出了建議。

Abstract:

With the development of science and technology, the demand for high speed cutting tools in machining is further increased, and the shortages of traditional casting for high speed steels gradually appear. Due to the characteristics of high alloy elements contents in high speed steel, the traditional production process of high speed steel is mainly die-casting. Although the quality of high speed steel produced by die-casting is relatively good, but the production efficiency is very slow. Continuous casting can significantly increase the output of high speed steel and save energy, but the central shrinkage of high speed steel billet produced by continuous casting is larger, and the problem of cracking in the rolling process can not be solved, so high speed steel continuous casting can not be formally put into production. Carbide is a very important factor affecting the properties of high speed steel, the addition of alloy elements will affect the size, morphology and element composition of carbides in high speed steel, so as to improve the quality of high speed steel. According to the mode of action, different alloy elements can be divided into carbide forming elements and non-carbide forming elements. These two kinds of elements have different modification effects on carbides, and the action mechanisms are quite different. In this paper, the main carbides in high speed steel are discussed, alloy elements effects on carbides in high speed steel and their research status are summarized according to different elements kinds,and some suggestions for future research on carbide modification of high speed steel are put forward.
