Improvement of Mechanical Properties by Means of Titanium Alloying to Steel Teeth Used in the
Ali Keleş Mehmet Yıldırım Gönül Coşkun
AbstractThis steel teeth and coupons were produced by the casting process. Steel having MC chemical content was alloyed with 0.15 (MC15) and 0.20 (MC20) % wt. Ti. Respectively, normalizing, quenching and tempering heat-treatment were carried out for improved mechanical properties. The typical lath martensite structure in martensitic steels was observed when microstructure of specimens investigated via an optical microscope. Mechanical properties of heat-treated specimens were determined to use of tensile and hardness test. Wear behaviors of MC, MC15, and MC20 specimens were found out with the pin-on-disk test device. The field test was done for teeth. Working life, volume changes of teeth were calculated as a result of this field test.
