|It makes students understand how plastic deformation influence mechanical , physical and chemical properties, the course content includes the following items: 1.The mechanical property change under all kinds of work degree for steel, iron and non-ferrous metal. 2.The comparative anti-corrosion test under all kinds of work degree for stainless steel(18-8 stainless steel) 3.The tension test of metal material, and how lubricator influences drawing force. 4.How work hardening influence tissue change at the tempering treatment, and how it influences crystal grain size. 5.The deformation simulation test under plastic thinmold operation and rolling & pressing processing. 6.Forging processing text. 7.The tensile processing test of plates.
