查询词典 hardening

The substantial behavior of the FCB material is introduced thouroughly in this paper. Generally, the apparent density ranges between 500 and 1500 kg/m3 while the compression strength varies from 0.1 to 1.5MPa. Because FCB is fluid and self-hardening, the flow value is often controlled at about 180?

Three kinds of cutting material were selected to machine stainless steel machining experiment such as ceramic cutting tools, cermets cutting tools and coated carbide cutting tools, in which the best range of each kind of tool material was founded. For example, LT55 was suitable to be machine lCrl8Ni9Ti as the cutting speed surpasses 120m/min and have a good wearable property.(3) Surface roughness was measured under different cutting conditions. Feed rate played the most important role in impacting surface roughness, and then cutting speed.(4) Chip patterns in different cutting speed with various cutting materials were analyzed. With the increase of turning speed, chip became shorter and was easy to be broken. For instance, serration chip appeared in high sped turning stainless steel with LT55;(5) Work hardening of austenitic stainless steel was analyzed.
