Structure and electromagnetic properties of ZhGr-type powder steel deformed by rolling with different porosity and temper
Source abstract
Abstract
The results of studying the structure and electromagnetic properties of powder construction steels of the ZhGr type with different temper (0.03, 0.45, and 0.95 wt %) and porosity (8, 12, and 18%) after deformation by rolling to the degree of strain ɛ = 30% and a step of 0.5–6.0% are presented. The data of microstructure studies that indicate anisotropy of the structural elements in the direction of rolling are presented, and typical types of pores are identified and described. The porosity value of steels with any composition is halved when the strain is about 30%; here, the maximal magnetization monotonically increases because the volumetric portion of pores decreases.
