Abstract

Commonly AISI D2 tool steel is used to carpet cutting blades in the carpet produce. Recently cryogenic treatment is performed to improve the mechanical response of various steel components. To investigate the effect of the deep cryogenic process on D2 tool steel, D2 tool steel samples and carpet cutting blades were cryogenically treated at -145 °C. The D2 tool steel specimens and the blades were treated in two different groups such as referans, conventional heat treatment and cryogenic process at -145 â°C for 36h after conventional heat treatment. The analyses were made for the purpose of determine the changes in the microstructure and mechanical properties caused by deep cryogenic treatment. The cryogenic treated and non-treated carpet cutting blades were conducted on acrylic, cotton and wool materials blended machine made carpets which were machine carpet with a pile height of 10 to 13 mm. The weight losses of each blade were measured as 2000, 3000, 4000, 5000, 7500 and 10000 m at the end of the cutting also the flank wears of blades were obtained by the microscope images. The cryogenic treatment of D2 tool steel has shown significant improvement in their properties. This improvement enhanced uniform distribution of carbide particles, reduces retained austenite, increase in hardness, increase in tensile strength. The cryogenic process showed that carpet cutting blades reduced weight losses. In addition, the wear of the cutting surfaces were seen to be less than non-treated blades. Consequently, the use of deep cryogenic treatment significantly improved D2 blades life and performance
