摘要

通过对高铬铸铁/低碳钢两金属进行碳钢包套约束,在Gleeble-3800热模拟试验机上,在温度为1050~1150 ℃,分别以0.05、0.5、5 s-1的应变速率,采用热压缩连接工艺制备了以高铬铸铁(HCCI)为内层、低碳钢(LCS)为外层的层状复合材料,系统研究了低碳钢包覆热压工艺对高铬铸铁微观组织及力学性能的影响.研究发现,在热压缩条件下两种材料实现了冶金结合,且不会影响基材原本的属性,高铬铸铁实现了良好的热塑性变形,材料韧性低的问题得到改善,提高了材料的可加工性.

Abstract

Through the high chromium cast iron/low carbon steel metal carbon steel sleeve constraint,the layered composite material by thermal compression connection process with high chromium cast iron(HCCI)as the inner layer and low carbon steel(LCS)as the outer layers on a Gleeble-3800 thermal simulator at the temperature of 1050 ℃-1150 ℃ and the strain rate of 0.05 s-1,0.5 s-1,5 s-1 was prepared,and the effects of hot pressing process of low carbon steel coating on the microstructure and mechanical properties of high chromium cast iron were systematically studied.It is found that the two materials achieve the metallurgical combination under thermal compression conditions without affecting the original properties of the substrate.The high chromium cast iron achieves good thermoplastic deformation,improves the problem of low material toughness,and improves the workability of the material.
