Planar anisotropy of commercially pure titanium sheetsQing-Dong Zhang,Qiang CaoSchool of Mechanical Engineering, University of Science and Technology Beijing摘 要:Commercially pure titanium (CP Ti) sheets show typical planar anisotropy due to the inherently crys-tallographic texture and manufacturing process. To characterize the planar anisotropic......
The Influence of Carburizing Parameters on Carbon Transfer Coefficient Tadeusz Sobusiak1 (1.Institute of Precision Mechanics, Warsaw, Poland) 摘要:Definition of coefficient of carbon transfer..., and actual surface carbon content".In this paper, a model is presented of carbon transfer from endothermic atmospheres to carbon steel. The carbon transfer coefficient values were determined......
